DigiTech GNX4

Unit is easy. Editing patches is easier in the Editor than it is from the unit itself. The manual is okay but the mfxsupermodels.com site has free vids on how to use this unit to it's full capability. My version is 1.3 since its newer (4 months).

I use a Peavey Classic 50-50 stereo amp and a 4x12. The settings are good but better when you have Speaker Compensation switches ON. Guys that review this and say it's all digital noise did not obviously have the speaker comp switches on. I had no problem dialing in sounds. I even added the model packs from the site with those vids since I heard they were really advanced and made for the GNX4. I couldn't belive how many amps, models, artists were on there. And all are extremely good. I had to tweak a few to better fit my guitar, but that was expected since i often did the POD and Boss GT-6.

To me, with the modeling, the GNX4 effects, mainly compression is a nice touch and not noisy as my other units. This unit is quiet.

I gig with it. 4x so far and I get more people asking me what I'm using and where all those sounds are coming from. It's cool!

haven't dealt with the Company but the forum members are great. If you realy want to know email guitar3456. he made those model packs and knows all about this unit. He talked to me 7 times before I bought the GNX4. Digitech should pay him. A couple months after I added the Hard Rock model pack and will definitely get the Ultimate Deal. You don't have to add the model packs if you don't want but i'm not an amp guru and I'd rather someone else make it. It's kind of like guys that wouldn't buy Sonar 5. Try and write that program, and see how much time it takes. The GNX4 is not as difficult or as harsh as people have said when you know HOW to use it. Free videos on that site helps. dramatically!

I play a very diverse set up. I like prog, alternative but can do other stuff. I'd buy this in a heartbeat if it were stolen. Love the unit!
I like that I know what all those functions are now. Watch a vid, boom it's on to creating the most versatile presets ever!! The GNX4 is a blessing to musicians who want to just rehearse tunes, record.. yes it's that good. Far better than Amplitube software and other less convincing. Buy one, buy the models packs is you want quick access to many amps. I shopped around with other pedals, and this one is a winner!

You can figure out some things by yourself, but it's much easier to just READ THE MANUAL! How easy...? If it were really easy 1. anybody could do it.. 2. people would b*tch about not having enough control/ability to tweak!
I just wish the presets were less of whatever they are!
I guess you have to be around a while to learn the 'less is more'
concept and DigiTech's main market is young.
So, as many have said, you gotta tweak, read, tweak.
The manual is very good.
I have ver 1.3 firmware.

I give it a 9 because the GNX3000 had better, more realistic amp emulation. I sampled it and only brought it back because it didn't have built-in recording- a huge plus- you don't want to have to lug and setup your laptop if you don't need to to record- you are carring enough gear as it is!

I've got more guitars than a man should have, but, I'm single with money to burn!
The Epi Les Paul Custom, the Hamer Ash SRV knock off and the Tacoma
acoustic with Fishman pickup, all sound great so far!
I played it live direct to the pa (no amp! the sound guys love that!)
I learned too late that you have to put the speaker comp on, so the rock patches were a little 'buzzy' as someone else said. But it actually sounded great on the 'Sweet Home Alabama' sounding songs we were doing.
So far I'm using good Sony headphones and a Roland micro-cube for practicing/recording. I'll use my Roland KC350 with it later.
Re Effects: I used to over use effects when I had cheap guitars and amps- less is more when it comes to effects! Like somebody else said use the amps, they sound great! Reverb's good. Delay's good.

Yes , it looks very dependable.
I plan to sell my Pod XT, maybe I'll keep my VAmp2 as a backup.

Very good online support.
Great web site.

Because I play nearly every style of music except Rap, a rig like this is great- very customizable. I play contemporary worship music and classic and soft rock.
I've been playing since '66= Beatle era.
I mentioned some of my favorites above. My best favorite is a Godin
LGXSA, it's a Strat-Paul, or Les-Strat. A real tone machine.
What I don't like about the GNX4 is that the GNX3000 has better, more realistic amp emulations but no internal recording/memory capability.
Marketing! The GNX4 is still in the pipeline!
So, to answer the ?, I wish it had internal recording capability.
It definitely helps me make music.

I bought this thing as an effectsprocessor to replace my Boss GT-5. One of the great dissapointments for me was the sound. Everything about the GNX4 sounds too harsh to me and the distortioneffects are in my opinion of very poor quality. Bybass, acoustic sim and everything related to direct mode (no speaker emulation enabled) created a high pitch tone. Also the Rectifier model had a very annoying high pitch tone that makes a Rectifier sound like a 8 bits sample. The acoustic simulator only provides crackles and distortion. I was reading in some of the reviews that you should always keep the speaker compensation switch enabled but in my opinion this sounds realy bad when using a guitar amplifier. And... for this money this thing should provide value for money and should sound good over a guitar amplifier. So bottom line... I think this unit sounds realy bad and it's very hard to find a sound to my liking.

Once more... Sounds are too harsh, distortions are bad, output is way too high for the presets. Direct mode provides high pitch tone. Rectifier model is realy bad with a very high pitch tone.

Anyone... please don't tell me I don't know how to work with the unit. I spend 3 months every minute of all evenings to find a good sound and only could come up with a nice Twin Reverb clean sound. Everything else was a complete failure. Warping, tweaking bla bla... nonsense.... Something for this kind of money should sound decent out of the box. I also read I should but the CD's with the models... Why? If a normal musician cannot create its own sounds with it then Digitech completely missed the point.

I think it will be a reliable piece of equipment. I owned a Digitech GSP21 Legend (which I liked far more then this GNX) and it still works perfectly after 12 years. I guess this thing will last too.

I asked questions about all issues I report here but did not get any decent answers. They told me to enable the speaker compensation switch on the back while connected to a guitaramp (straight into the FX return) to get rid of the high pitch tone. Well... this is merely filtering out what should remain. Yes... you loost the high pitch tone but you it will also such the life out of your sound.

I play symfonich Rock and it did not fit my needs. I wish someone accidentaly would break it (but then you would need a truck to drive over it and it probably would still work) of that it would be stolen... I sold mine on the internet and bought a GT-8. This Boss GT-8 has everything the GNX4 lacks. GT-8 rules and is far more better. It does not have the features but provided the sounds you need.

Sound is great. I did use the speaker compensation switch and it was ten times better. Editing patches is fantastic. Now that I have the Supermodel pack and the vidoes on how to use this I LOVE IT! I went from a few amps to hundreds of amps to choose from. Awesome. Thanks MrG3456 at Digitech Forum. My friends cannot belive the sounds. Our rythym guitarist returned his POD for a GNX4. We're really happy now. He uses one tone and I use another so we don't have to compete!

the manual is okay but the videos at mfxsupermodels site really really help you understand the full potential of this pedal. Digitech owes this guy and I'm sure he has helped them sell a lot more of these!

My firmware is 1.3 and is current

Once again. It's awesome. For direct recording it is unbelievable easy to use. The sound effects are really good but once again after reviewing how the Supermodels patches and amps are setup I can easily create MY OWN SOUND. Mix a Mesa with a JCM800 and hit that warp button. Its too cool. By itself the patches are good, most kinda show off effects. The ones on the Super pack are dead on! Lynch, EVH, Yngwie, Clapton, ACDC and more.

the effects are nice but again, go to the sites and learn about how to use them. Too much is often too much.

Ive played live about 3 times since I had this. It sounds great and I think its built pretty nice. I take care of it though. Its an investment.

Cust support I have not used for the GNX4 itself but did for Protracks stuff. I think its very good though. I have to add this though. The support on the Super models pack is superb. I emailed the service guy 4 times in one day and had responses answered in the same day. I was shocked to see the times of the responses. Must work in shifts! The Ultimate pack gives 2 yrs of upgrades. Monthly patches, more amp models, cabinets and more since last November.

I play almost every kind of music in a cover band and wedding band.
I've been playing for 12 years and use a JC120, DSL live. I would for sure buy this again. At first I thought the stuff on here was complicated. Watch the public and free videos at the supermodels site. Learn all about your pedal and take advantage of all those control assigns and extras the manual does not expand upon.

I compared this to POD XTL and took the POD back. The GNX4 has so much more to offer and the modeling packs really sold me. My friend has a POD XT PRO which I like but he liked the GNX4 and Supermodels much better than his precious rack baby! I can record a song so fast and jam to it in less time than it takes most people to hook a mic or guitar to their computer. I don't have to lose ideas on paper. Arm the track and voila !

last thing to add. hmmm Get the Supermodels packs. You will not be able to see your family. Over 1000 models and patches along with over 180 artist presets that will make your jaw drop. I love Jeff Beck sound and another one that super models nailed. So many dozens of amp manuf folders containing many amps made by the mfg. the models are really that good! I add a slight mix to our PA sys and pan for effects spacing and it sounds awesome! A MUST HAVE ! The difference is night and day! The videos, GNX instruction, usage text, will have you finding tones you never dreamed of having.

Overall I give a 9. Add the Super Model pack and it's a 10++++++++

Easy of Use No Biggie and then again .... !

Patch Ediing is something I learn next but am not intimidated .

Like most manuals it isn't enough but it's good enough . Aside from my nephew's & my manual coming apart after re re re reading the stuff in it I guess any paper back magazine time manual will show signs of use ( like al my other music books , they look thoroughly used )

I'm lucky since the latest firmware update is already in my unit , my nephew's is not bujt wikth my computor I will up load it since he has no p . c .

I am and always will be a tube man at heart

- but -

This unit makes you rethink it . I know it sounds really rightous when plugged into a super clean P .A . I have a ( pairs ) folder horn with a 15" speaker and a pair of Altec Lansing horns hoioked to 400 watts of power amp ( I have other P. A. amps with more power but this is my big gun over all for most rooms )

As for settings :

As I have read and experienced , yoyu have to " tweak " the settings to get what you want out of them , God help you if your a newbie and don't have a clue on amp & cab sounds :(:

With a Strat , a Godin LGXSA & my Washburn D46SCE acoustic electric and a little Hondo nylon I get my nut playing my ass off . For recording the Washburn & nylon I am saving up to get a good mic , but Washburn direct to a mixer and then into my GNX4 works smoothly and nicely . The Godin & /Strat kill plane and simply put .

As far as effects & aviable stomp's

- WOW -

They get nothing put praises form all who have listened to myself & my nephew on his as we fire off on our units together , man a pair side by side izzz trully a killer set up to behold . What I lack in speed my nephew cooks on , what he lacks in experience for grace , smoooooveness and just tasties stuff well , that's where this man comes in to the picture :)

My nephew has customized a whole bunch of new patches and I'm doing that to mine now and will make custom patches for harps too . All these user presets we make can iether go into the users presets in the GNX4 or the CF card .

Looks like even if it failed it would be a terrific boat anchor ! Wow is this thing built like the proverbial brick - - - house :) I would gig with out a second one personally as Digitech has a track record of great performances night after night with out fail .

So far I pestered the holy @#i& out of Harmnon Kardon ( that's who owns this company and if you know HK stuff well you know they put out a quality product now for years and years ) before I bought one , I called and called asking questions about the GNX3 first and glad I did because I know I would not have liked one for my playing / recording applications .

I worked in a high end audio service and repair many years fixing stuff like the very best you could buy in audio electronics from Reel to Reels MaCIntosh tuners , pre amps & poewr amps , Yanaha under warranty ( they were super tough to get approved as a indipendant qualified service center like MaCIntosh ) , as I recall Digitech alwasy sent parts for repairs in a timely manner so yeah I trust Digitech .

I izz eclectic as caviar & peanut butter & jam . Sushi & Mexican Food , and my music is as varied . I play Blues , Jazz , Rock ( and it's many flavors one of which is one is " Rock-A-Billy " , I work and record with Chan Romero a real Rock-A-Billy legend ) , Country Western , Boleros , Hawaiian , and even some Portuguese stuff out of Brazil .

I blow harp ( blues harmonica to those who don't know the real name for a 10 hole diatonic harmonica :) since 1954 & I'm 55 :) I also play drums , trumpet , keyboard & guitar too . This unit has so much potentional for the guitar right (??) also as a modleing amp for Blues harp poses a real potential as well so yeah it's a marriage made in high fedelity harp & guitar heaven fo diz dude .

I have alarms & 2 guard dogs ...... No one better try and rip this off ! If it somehow sprouted new legs and walked off I would buy another as fast as I could , maybe the next generation one :)

With 8 tracks to use as a recorder , and the stand alone midi drummer it's a deal , throw in the stomp box's & modeling potentials plus an USB interface to your computor that lets you also use it for midi importing and exporting to the CF card ( like jpgs & other stuff a GNX4 doesn't read it self ) , a MP3 player , midi & songs storage as well as edit your amp & cabinet models along with song editing , it's a no brainer .

I compared TonelabSE , M-Box ( Black Box @$200.00 ) & a few other garden variety stomp box's , digital recorders , & nothing came close for universality quality & price .

Whish you could slow down the MP3's you load in the CF card , that would be super dooper . With a software program ( it comes with mac & p . c . ) or other stand alone learn a lick type you can do this although it's the " long way around the mountain " if you get my drift .

I thought out a similar unit for computor based recording in the 70's , and it came out back then and I wasn't able to afford it . Now 36 years later ....it's here and it's afordable in the GNX4!

I knew a unit like what I thought of would allow the music that's slamming and bumping about the insides of my skull to be not only let out but archived , my time is now ! This is the really big reason for the purchase , I wanted a recording device , it could have been a Tascam D88 DAT 8 channel recorder if I could have afforded it , now with this unit it goes way out and above a D88 DAT or a ADAT or what ever single type recording console with out modeling amps & cabs or the FX of the GNX4.

This unit is THE unit ( bottom line entry state of the art digital musicians workstation ) for the 21st century performer(s) .

For the negative posts I have read here on this unit ( and not many to be truthful :) , it's apparent that some were just popping off to hear themselves and more than likely did not ever own one of these bad boys . Only a blind , deaf , and speachless person would not find the genius in a GNX4 waiting to pop out like a genie in a bottle .

All you need to make this work is this :

# 1 : A electric and or an electric acoustic guitar with the appropiate cables & stuff .

# 2 : A nice power amp and or P . A .

# 3 : 2 healthy arms & hands & 10 fingers ( although Django didn't let a little problem like missing fingers on his left chording hand a biggie ..

# 4 : Ears & eyes that work reasonalbly well .

# 5 : The ability to read and comprehend .

# 6 : An unquenchable desire to play music and also write music too .

# 7 : Dedication to practice ( you know who you are ) .


Following through with all the above will make it an experience to remember !

I be seeing ya'll somewhere along to ole sound scape horizon partners Yeeee haaaaaaaa !

I have had a GNX4 for a wee and a half now. As a family man my time and expenses are limited. The sales guys at the brand new guitar center in Appleton really didn't have a clue about what this thing is or really anything else they sold. They were nice guys but not technically up to the products. Now I'm a mechanical engineer with a real thirst for knowledge and study the SH*$ out of everything. I spent a lot of time on the internet. Every detail must be worked out. I am also one of the cheapest people you would ever meet.

It took a while to figure out the presents and warping features. Maybe half an hour to an hour between the manual and my three little kids.

There is a great tutorial at gutarworkstation.com and an available power users manual written by the same guy.

Pro Tracks is a complex program with a lot of capability. It has more features than I will probably ever use but I am going to try. The help menu is OK but could be better. I bet the keyboard guys at the guitar center could help with problems more thatn the guitar guys.

The user community is great.

I use decent Sony headphones. My amp is a P.O.S. but will play the sound. I plan on getting some powered monitors and hooking directly to the GNX4. I do not play out. This is just a fun toy.

It took me a few days to realize there is a button on the back that acts as a high frequncy filter. If you don't like the sound turn this on.

Everybody is right, the presets aren't the best. Thank god you can put 80 of your own in. Again the on-line community has added a lot to the web. Also the gutar magazines are posting their pre-sets. it takes about 2 minutes to find, download, and add to the unit. Use this feature.

The drum kits aren't the greatest but they are good. I found that I can download midi files fromthe internet, import into PTP and they work. Good time saver.

There is a guitar to bass preset. Not that good at all. My brother plays bass. I'll try his soon.

This thing looks like it is built to last.

I haven't tried digitech per se but ther website links to users. There are a lot of knowledgible people out there.

I had probelms with X edit. I had to update the software and actually download a .dll file and insert it into the directory. Simple enough to do if you can use a computer. GNX4.org again helped. I'll have to send that guy a donation.

I mostly play rock. This unit will play everything.

I have played for 22 years. I don't have much gear. My favorite guitare is an 89 strat plus. Nicest strat I have ever played. I am going to sell the rest of my effects because I don't need them anymore.

I would buy this again if it were stolen.

I looked really hard at the Line6 Toneport and M-Audio Black Box. What drove me to the GNX4 was the software pro tracks plus. The other units come with relly limited recording like 4-tracks and some midi. Looking at the total cost of another unit and software AND mic inputs AND ability to use live set me straight. The GNX3000 is also a great unit if I knew more about it I may have gone that way. There is a website like gnx4.org that will help explain the differences. I wish I knew it was there before I bought this. I think I'll keep the GNX4 and not switch.

I wish there was better documentaqtion for the Pro Tracks plus. I wish it had the capability of using a midi bass like it does for the drums.

I have lost the drivers a couple of times when powering off and on at night. I just reload and it works again.

For an idiot like myself, the learning curve was not too bad. I must admit that I got stumped and had to search the manual many times before I figured the whole groove out. Then again. I have been told that I have adult A.D.D.... Oh look! A chicken! Uh, what were we talking about?

I use the GNX4 primarily with a very nice set of studio reference headphones, and the world's best custom hand made guitars. Kids; do not try the GNX4 at home through your amp without reading the manual front to back at least twice. If you have heard about tones that "suck" then you can almost guarantee that they were heard through an amp with the "speaker compensation" switch set wrong, and the signal path all messed up. The effects in general ~are~ somewhat unrefined right out of the box, but can be incredibly easily tweaked with Xedit and a computer. The knobs and controls on the unit are not very hard to use either. I sat down with it, and downloaded about a hundred patches from the internet, slapped them into the GNX4, and jammed away in under a half an hour.
The amount of control you have over any particular sound patch is nearly limitless, and you can save, change, morph, and warp sounds until your eyes fall out.

can't speak to durability, as it hasn't given me any problems. It is very well made though.

Great match for any style of music, as there are literally limitless tones available to make as you wish! I have been playing for about 30 years, and have had all sorts of gear. This is without a doubt the Bombzilla of all time all effects pedals. Awesome. If it were stolen, I would hunt the muthafu(#3r that stole it down and kill him with my bare hands, and then eat his heart before it stopped beating. If I had to buy it again, I would sell my left nut to get the cash. (Well, I AM passionate if nothing else...)
Best pedal out there. I could not think of anything else I would like this unit to do, except maybe dispense 20's?
As to making music, I have not been this inspired since I bought "Desiree", my black Charvel Strat 20 years ago. I feel like a guitar god. Throw in all the recording ability, and the excellent software, and you can't lose. The drum machine supposedly rivals a stand alone unit, but I beg to differ. I ~have~ a stand alone unit. The stand-alone Roland I own is crap compared with the versatility of the unit in the GNX4. What they don't tell you is that not only can you play patterns off of the web on the GNX, but Protracks has an INCREDIBLE drum track editor right in it! The actual drum sounds could use some love on some of the kits, but the rock kit is pretty darned close to real sounding. As to "looking for the chips" as they say, good luck. I didn't really believe the drums 100%. They always sounded like a drum machine to me. To the unit's credit though, I feel the same way about my stand alone drum machine, which cost more than the entire GNX4 and all the accessories. Anyway, I can't easily be fooled by any machine.
I have only had this machine for a bit less than a week, but I have gained the confidence to set down some demo tracks, which to me, sound almost as good as the stuff you go out and buy on CD. With some time, I am certain that I will put together an entire solo album just for fun. Does it compare with the audio quality that you could get in a $2000.00 per hour studio? Fu(# no. Then again, the whole rig with nice set of headphones, and an AKG studio quality mic cost way less than half that much.

Takes a few minutes to figure out but not hard to get great tones out of.
editing patches is fairly easy once you learn the buttons.
manual is simple

I bought this initially for my Studio. I play Les Pauls, Wolfgangs, 1 Ibanez, JSX w/XXX cab, Cybertwin w/412 cab, Mesa combo. I own a Pod XT Live, Tonelabs SE, GT-8, GT-pro, Zoom gfx-5. Why? Different tones for different stuff. They all have a strong and weak point.

But honestly, this is a great pedal. Let's face it, Digitech has done a great job knocking down the competition in regards to all out rock & roll pedals. I'm talking grunge, metal, crunch and just plain solid rock & roll.

It has very usable effect for live or studio, but if I don't like an effect sound out of it, I'll just plug in an effect I do like (loop it) and mute the one on the pedal. That's simple use of the human brain to attain the tone you are looking for. We've beome a lazy music generation in regards to tone.

Did someone forget to teach the fact that "tone" comes from the hands and mind of a guitar player. His gear does not "make" his tone.
So if you can't get any good tones from this pedal...take some lessons. :)

Pretty indestructable.

I had a problem with the software (X-Edit) with this product but Digitech did contact me back several times.

I play mostly Christian Rock and worship. It does a nice job especially for heavier rock parts and records direct into a console nicely...very heavy sound.
I've been playing for over 35 years. 20 professionally.
I would buy another one if this one was stolen.

I love the tones in this for rock stuff. Also has some cool delay stuff. Favorite feature is the drum machine for just flat jammin' out with headphones and then you can record it with the built in recorder..how cool is that?
It doesn't compare to the PodXTL or the others I own as it is it's own creation.
I think it is equipped with what it needs and no more...this will help you make music and won't get in the way.

NICE JOB DIGITECH. YOUR PRODUCT IS FLAT AWESOME.

It comes, stock, with factory presets that are fun to play, but you'll want to edit them to get your sound.

It's a lot easier than I thought it'd be. Once I figured out how it works, I was editing All the presets and having a blast.

The manual is great! I like trying to figure things out on my own and when I get into trouble... go to the book. I flipped right to the page and my questions were answered quickly.

There are downloadable presets from users on the web page. That's great! You can go to their forum and get help right away. A great group of people ready to give their advise. For all of the above reasons I give it a 10+.

I use Gibson Les Paul Humbuckers, Les Paul P90s, Fender Clapton Strat, Strat with texas specials. For amps, I use a 1971 Marshall Super Lead 100 with matching 4x12 (vintage 30s) and a Fender 1965 Twin Reverb. It is dead quiet. It makes the sounds that it is supposed to and nothing else. I'm the one that makes all the nasty noises. I connected it to some JBL G2 powered cabinets in stereo. MAN!!! That is the sound! I was amased! Great separation for the effects and a big full sound just like wearing studio headphones. Clear, Clean and Big.

I've owned/played Digitech equipment for years. My first multi-effects unit was an RP-1. Now That one was hard to program... but do-able.

I've had no problems with any of their products and don't expect any from this one.

Years ago I called them about a new manual for the RP-1 and they sent one right to me... they even sent a cool digitech sticker. Nice people.

I play both kinds of music. Country AND Western. JK

I've played in Metal, Disco, Show Bands, Country, Bluegrass, Blues, Classic Rock and Grunge bands steadily since about 1968. I like veriety. I like em all. uh... I don't do rap. (no disrespect)

I own old vintage pedals from the 60s... Fuzzfaces, LPB1, LPB2, Vox wahs, Big Muffs, Ibanez, MXR scripts, Boss, I've built many of my own over the years ... every Fulltone made to date(Mike does a good job) Heck! I don't know what all I have in there.

I don't know if I'd buy it again... I probably would because I travel and pack it in my luggage. I have my Les Paul with me now. That's the real reason I bought it. I can sit in my room with some good headphones on and record riffs... good drum machine. I even have a SM-57 microphone to sing into.

I've been trying out guitar effects since the 60s and don't imagine I'll ever stop. I hit every music store I see and try everything I can get my hands on until they kick me out. I chose this one because it's a very well built machine and does more than any of the others I've tried and Digitech does it the best. I hook it up to my laptop with the, provided software, and record tracks and manipulate loops and create songs to burn to CD... before I know it, it's time to go to work the next day! It's addicting. I didn't get the extra footswitch (for recording). I wish I had. I'm going to see if I can get one when I get back. I'm in the Persian Gulf right now and am Very glad I have it with me. If you're like me and need everything in one package, this would be a good buy. Now let me say this... It's, probably not going to take the place of a big pro recording studio... The effects are better than any of the other new processors, but it is very convincing sounding if you don't have a world class studio to compare. I have no doubt that it'll do very well playing live.

You may need to buy a big ol CF card for recording. I bought a 1 Gig.

Good Luck, if you're planning to buy. I'm happy with mine.

Firstly, this product is not for those who are even remotely technophobic. If you are used to plugging in to your favorite amp and turing two knobs, if you are not prepared to read manuals, consider something else.

The GNX4 gives you control over EVERYTHING. Absolutely everything. There is no way you can have both control as well as ease of use. The tuning of the cabinet, the crossover between the woofer and the tweeter in the rotary speaker, the properties of the room that you reverb is caused by and i know i'm forgetting something. Digitech has done a brilliant job of making such control in a fairly easy to use package.

Editing patches is easy once you get used to the layout.
Manual is great - covers everything (its also about 3/4 of an inch thick)
What is best is the ease of which you can create backing tracks good enough to perform with.
Recommend you have a computer that is suitable too, because you miss out on a lot if you dont.

I am using the GNX4 with a Gibson SG and:
a) a marshall 30 watt 1x10
b) headphones
c) A poweramp and a quad

however it would sound best thru a neutral sounding PA

It has the best noise gate i've come across, so it is quiet as a mouse.

As the GNX4 does what you tell it to do, the tweaking is up to you. You need to know what you want, how to make the sound you want. Once you know this and make you patch, it is comparable to the amp that it is modelling.

A refresing change is that the GNX4 encourages you to create your signature sound by combining the characteristics of two amps of your choice.

Quite quickly i created the tones for my fav artists: Iron Maiden, Metallica U2 Led Zepplin etc.
What is best is that there is a forum that you can ask for help of any kind and people have posted their patched there.

Everything is as good as you can get except maybe the Talker is not as good as a traditionall talkbox, and pitch shifting in very high shift amounts (- 2 oct, + 2 oct).

Right. You could easily kill someone with this. It is made out of 3.5 mm thick sheet metal and is solid as a rock. It weighs alot which is good so it doesnt slide around. There is now way you could break it at a gig except if someone smashed the knobs deliberatly or if you stepped on the screen/knobs with your full weight. It is very solid but i recommend a hardcase ( i made one myself)

I have gigged with it twice, rehearsed many times. It has water splashed on it and it was fine.

Yes, i would not consider a backup.

Hanvnt contacted the company, havnt needed to.

The best resource for ANY question or ANY advice is the guitar workstation forums. There are over 700 members that are all users of guitar workstations, many whome are very knoledgabe. Any questions, go there.

I play rock, metal, blues. The GNX4 can do everything - it suits me perfectly.
Playing for 6 years, relevant gear: a strat, SG, a quad, 2x12, poweramp and little practise amp.

If it were stolen or lost i would be very sad and make myself happy by buying it again.
I love everything about it, especially the fact that you can backup/organise patches on you computer so you can customise if for each gig.
I always shop around and i did for this as well. The GNX4is the ONLY product that has everything you need in one unit for a good price.

I wish it had...un.... maybe another expression pedal, but since each control footswitch can control up to 3 parameters at once there is really no need,

It helps heaps with creativity as you can record your ideas and hear them later and improves soloing because you can play to backing tracks.

Ignore 1 ratings. These people are either idiots, cant play guitar, have no idea with technology, or have no ear for tone.
Any questions email me. PS no i do not work for digitech.
