I use an Ibanez SA160AQM with Seymore Duncan Dimebucker in the bridge and Seymore Duncan Little 59'ers in the neck and middle positions. I run it through a Peavy 5150 4x12 wired to 4 ohms.
This guitar sounds great through the GMax 100. The distortion channel is awsome. Tons of gain and it sounds better than most tube amps I've heard. I added a BBE Sonic Maximizer and a DBX 31 band Eq in the effects loop and MAN! did this amp come to life. We play music in the style of Godsmack, Sevendust, Disturbed, Alice In Chains, etc.
We do a cover song by Puddle Of Mudd called "Drift and Die".It requires a accoustic, so I ran the Ibanez SAI60A into a BOSS AC accoustic simulator pedal straight into the input jack on the front pannel. Switched to the clean channel, added a little chorus and reverb, and wha -la. It sounded like a Miked up Jumbo Taylor accoustic. OUTSTANDING! The built in HUSH system is great. Works perfect. It keeps all the hiss and hum from the lighting, high gain channel and effect perfectly silent at all times without effecting the tone or gating on and off. I wanted to take the back off of this amp to see if there were any tubes inside. This amp get's LOUD and it has major low end balls for drop tunings. The BBE really helps here.

Can't beat it. Don't need a backup. It's solid state. Just plug it in and play. Unplug and load it up. It got knocked of the top of a 4x12 cab at a bar one night by a drunkin stage diver while it was being played through. It finished the song upside down on the floor without missing a beat. Try that with a tube amp!

This amp is built like a tank and it's solid state. It has a three year warranty. I don't need a backup and I will probally never have to call them.

I have been playing for 30 + years. This has to be the one of best solid state amps on the market today. The only thing that comes close is a Randell V Max or Warhead. This amp is right there with these guy's and it's a $1000.00 dollars cheaper. Stick that in your pipe and smoke it Randell. lol.
If it were stolen or lost I'd buy another one in a second! The only thing I wish it had would be a seperate Eq with sweep mids on the distortion channel. I took care of this problem with the DBX Eq I run through the efx loop. The clean channel sounds as good as good or better than a Roland 120 Jazz Chorus.

solid state 100 watt head,two channels,like having three with the boost,this amp for a solid state will rip your face off,only one EQ,but its so versatile that it really doesnt matter,the clean sounds good either way,so far its been plenty loud,i havent had the guts to rtake this thing past 6 and a half,i use all the features this amp has

i have an epiphone les paul custom from back in the day,this amp with my guitar is freakin awesome,i played it the other night with a strat and it rocked hard with that too. i am in a band called moving co.,and we are hardcore/new wave punk/reggea and this amp seems to be ideal for what i am playing (even when i have my big hair metal lead streaks)it has more than enough distortion to,a friend of mine said it didnt have enough,but if you heard how he likes his amp setting you would understand,the louder it gets the meaner it gets,makes almost n noise with the "decimator" thingy,i would take this amp over a marshall any day,even though its solid state,it will rock out most marshalls.im running the head the a peavy ultra 4x12 cab and its does the job with this amp

the guy that sold it to me said that,the guys make these amps with top of the line components,and so far it shows i would not need a back up for this monster,it has a waranty on it,only had it a few weeks,but am gigging with it in a a few weeks.

i think a few years on the warranty,bu havennt dealt with them yet,hope not to

running this with a les paul,a peavy ultra 4x12 cab. dude if this amp was stolen,first i will find the man who stole it(that wont be hard to find,im the only fool in town that owns one),i wont hurt him real bad,but i will let him know whos amp it is,and if the guy could run that ffast with the amp in his hand,i would definitely buy another one ,i love everything about it,sounds so good,looks pretty cool,cant beaat this,i suggest anyone who likes amps along the lines of marshall or boogie(sorta) should consider getting it man,best of all,cheap enough for the poor white man such as myself

The 2 channel setup is somewhat limiting, esp since there is only a master EQ section. I'd also like for it to be stereo and maybe have a (foot)switchable FX loop.

Removing the back cover revealed an accutronics spring reverb housing (connected but, somehow, non functioning) and all wiring is mounted on a PCB.

I've only had the amp for a day and plan to follow up with at least one more review, after I've had to chance to test it at high volume, with a Strat that I'm getting in a week, and with my Digitech ValveFX processor that is currently at a bandmate's house.

I've so far tested this with a Steinberger Spirit GU7R Custom with a Kramer Quad-Rail pickup in the bridge position, and a coil splitter installed on the neck EMG Select humbucker. Middle pickup is an EMG Select "Single Coil" style pickup. Bridge pickup is (unintentionally) wired out of phase. Test was conducted with Guitar->Amp->Laney 2x12 cabinet.

With the bright switch engaged the clean is truly awesome. Imagine a more sparkley Fender Bassman with better clarity. It doesn't have as much "character" as an all-tube Fender Twin for example, but remember, this is a 100% solid state amp. Neck humbucker, bright switch disengaged and some EQ tweaking you can get a great warm jazz tone. If you have a very high output pickup you can get the clean to distort, but otherwise it truly is clean all the way up.

Lead channel, boost disengaged, the distortion ranges from a slight clip to a warm crunch to a very saturated tube-like distortion. Hit the boost switch and you've got more gain than any distortion crazed metal head will ever want. Extremely versatile.

The EQ is what really makes this amp shine, its wired before the gain circuitry and it's active allowing for boost or cut of each band. Using the gain and EQ controls you can get anything from a Marshall JCM800 crunch, to a Mesa Mark IV, to a Peavey Ultra 120/Plus/Triple .

The "Decimator" noise reduction switch is hyped a bit too much by the company on their website (www.isptechnologies.com) It is extremely transparent when engages, but, for my purposes, the threshold is a bit too low. 60-cycle hum from a single coil pickup will usually get through. However, it really is a freebie, and it's transparentness will please people who normally wouldn't use a gate anyways.

I'm not giving an opinion because I've only had it for a day. But it has been through a lot of abuse before I bought it. It survived a few tours and, from the look of the cabinet, has probably been clubbed by a stray mic stand or whatever a few times. Plus, it's solid state. From indirect evidence alone, this would probably get a 10.

Bought it used, haven't had to contact the company yet.

If it were stolen or lost and I didn't have the cash to buy a Carvin MTS series head or similar, I'd look around for one of these. They're quite rare, tho inexpensive, so I probably wouldn't be able to get one. Of course, if someone were just to see the amp or read the spec sheet w/o hearing it one would think it's a complete peesashit. My friend got one a few weeks ago and he showed me the specs and I was like "WTF, why would you want that it looks crappy" but I heard him playing it later and was quite stunned by the tone. I can honestly say that this is very likely the best solid-state, non-modeling, amp you can buy. It's so versatile that I wish I could store and recall amp settings via midi so I could use all the tones live. Only downside is the limited control over individual channels, but for the money it's easily forgivable.
