Korg DTR-2

Pretty easy to use. I didn't have a manual and I figured it out just fine.

Ibanez Prestige SR1005EWN>Line 6 X2 XDR95 wireless>DTR-2>Carvin R1000. It isn't noisy and it doesn't effect the tone in the signal path of my bass run with no effects, but at very high volumes I notice a popping or clicking noise. Not good.

It could be used without backup, but beware of the clicking/popping if you're playing live

Didn't deal with them.

I play rock music. I've been playing for 6.5 years. If it was stolen I would by something else. I'm going to buy something else anyway because I don't want clicks and pops while I'm playing live.

Its about as easy as it gets. I run mine through an Ampeg svt4pro via back panel tuner out. Lights easy to read even in darkness. Display is bigger than the Behringer rack tuner.

Sounds like its not even there if you have it in rack not as opposed to your signal chain. I think thats why people think its so noisy, I havnt heard a peep.

I bought this used so I know it is reliable. The only thing that seems like it could break is the power button, but I doubt it. I would depend on it without a backup but I have not had the unit for very long.

I was looking for a rack tuner with decent display, reliability, lower in cost, and sounded good. This was a great buy at $45, I dont think I would have thought so if I spent around the $100 most of you are paying. So if you can find one used, pick it up you wont regret it.

It's a tuner.. anything else??

Ok now, I read all of the reviews below, but I failed to understand people who continuesly b..ch about how bad the hum is. First of all, I really don't know if it is noisy or not, because I never put it on my signal path! If you are such a purist, why do you keep insisting placing it on yours. *Any* tuner will have at least a buffer and that buffer will effect your sound.

It's metal and I like metal :)

Even the picking strength effects the LEDs. It's extremely sensitive and captures harmonics more than it suppose to and almost impoosible to see green color lighted up by itself, without the company of a dimmed red LED. I have other tuners, they show that guitar is in tune. but then I plug into the Korg and see that it is not. with a floyd rose, it is even more unstable. I am not sure that level of sentivity is good or bad. Other than that, yeah, it is accurate :)

I find this to be a very dependable piece of equipment. I almost hesitated to add this to my gear based on some of the reviews I read, but to the contrary... I have had nothing but good experience with it. It couldn't be easier to use. Input/Output jacks on the back panel and another input jack on the front. Mute button on the front panel for quiet tuning. Easy to see LED's allow for quick spot tuning across a dimly lit stage.

I have experienced no adverse noise at all when the DTR-2 is engaged.

Just got it a couple of weeks ago, but so far so good!

Haven't had occasion to call.

My advise to those that are shopping for a good , dependable rack mount tuner... find a good used DTR-2. I do not know about the newer versions as I recently acquired my DTR-2 used. I just bought another one today on ebay. I hope to have the entire band outfitted with them soon.

Easy to use, if you cant figure it out you're am idiot.

Ive used this thing in front of a bunch of guitar rigs in the past 110 years, Marshalls, Recto's Soldano's and NEVER any noise or problems at all.

I purchased it new around 1995, NEVER had a failure of any kind.

No idea, never needed them.

I play in a working rock cover band, have used this tuner for over 700 shows in the past 10 years, everything from small/large clubs to massive frat parties....and the tuner never had a problem...not once.

This is the worst tuner I've ever owned. It's a pain in the ass to use, because the led indicator jumps all around, and is not stable at all. Seems like the tuner picks up way too much harmonic content to give an accurate tune. Not to mention that it takes twice as long to tune your guitar as is should. This might not be a big deal if you're just using it at home, but when you're at a gig, and you need to tune quickly, this thing makes me wanna pull my hair out.

Low marks again here.... I was really surprised by how poor this tuner works, It intrduces soooo much hum into my guitar rig, not to mention that it sucks the life right out of my guitar tone. Anyone got $5 they'll give me for this piece o crap? I paid $150 for this thing, and My little Sabine STX 1100 works a million times better. Unfortunately the little Sabine doesnt lend itself to playing out live on dimly lit stages. Otherwise it would be velcroed into my rack.

Well as bad of a tuner as it is, i can say it is reliably crappy.... It's never broken down on me.

I play a Les Paul into a Mesa MK IV, in a Classic/Modern Pop rock coverband. I'm really looking for a good replacement for this tuner, cause i hate this thing. Hopefully the Sabine Rack mount tuners work as well as thier little handheld tuners, cause that's what im probably gonna get.

If you need a good Rack tuner... dont buy the Korg DTR 2..... What a piece of Junk.

This unit is very easy to use, as are most tuners.

This unit is quite weird.... it makes noise sometimes and sometimes it doesn't. Makes no sense to me. When it does produce noise though the level is pretty awful and is totally unacceptable. When it works though it works good.

No I cannot depend on this thing. It is too much of a gamble.

The unit looks nice and it works nice..... sometimes. Sometimes I feel like throwing this thing up against the wall when I get this constant "hum" going through.

I got this without a manual but it is very simple to operate so I never needed one.

Used in my rack, taking its signal for my Ampegs Tuner out socket.
Totally silent as you would expect.

I'm a pro Bassplayer and this unit was used for two years, averaging 5 nights a week with no problems

Had no need to contact Korg.

I no longer use a rack setup so this unit became obsolete for me.
I could not recommend it more highly, especially for a pro or semi pro player.

Very easy to use & see.

This is a second tuner I have recently purchased and I am using it in an effects only rack patching it into a MARSHALL TSL 2000 and a MESA DUAL RECTIFIER THREE CHANNEL SOLO HEAD. When I noticed a loud 120 Hz hum I first thought it to be bad filtering in the power supply of the unit (I do electronics repair), so I brought it to the shop and upgraded the filter cap before the 5V regulator, I need to mention here that the measured noise was well below what I expected to find, so I also installed a "GND LIFT" switch at the rear panel, and since this unit is going to be grounded by the rack mounting and by the audio interconnect leads I did not see a problem with safety. I cannot recommend this though obviously for liability reasons. Anyway, when I reinstalled the unit in the rack the noise was still there just as before, but when I switched the ground switch the noise was gone! Apparently with its internal power supply which utilizes a three wire power cord it became part of a ground loop. For reference I do not have any noise problems in my other rack using my other DTR-2 tuner which is factory stock, no modifications...go figure...
All in all, with the ground loop problem solved it has very little noise now and works quite well even in front of the high gain channels of my Marshall's and Mesa's. By the way, many manufactures use "wall wart" power adapters these days to power their rack units. I believe this unit would not have had a noise/hum problem if it were designed with a wall wart, but personally I think a wall wart design is cheap.

Yes I believe this unit is well constructed for consumer grade equipment, the parts are laid out very well, it should be fairly rugged.

When I called for an updates or bulletins on this problem KORG was very polite, friendly and wanted to help. As far as a downloadable manual for this unit though, there is not. This is something KORG should have at their web site even though the unit is pretty simple to operate.

Once again, the mods I made to this unit are not recommended for liability reasons, that is not to say that other equipment on the market is not designed this way. Some people have used a three prong plug adapter to "lift" the ground pin of their equipment which is what the switch does in my unit...

This acts pretty much the way it's supposed to do. No fuzz. Come on it's tuner! I use it every evening I'm out playing as it sits in my live rack and I've never experienced any problems.

I'm running my Stingray 5, custom Jazz, Yamaha Nathan East etc. tru my flooreffects and into my SWR SM-900 into a SWR Henry the EIGHT 8*8. The Korg and a tubecompressor sit in the effectloop. The SM-900 has a tuner output but I'm not using it coz there isnt a muteswitch on the amp. So I'm using the mute on the Korg as standby and tunerswitch. I haven't noticed any soundloss nor noise as the other here states. My guitarplayer has one too - no problem there either. It tunes everything - all my basses ( 4,5 and 6 strings, fretless you name it)I even once tuned a doublebass - no sweat! The rating I give her is becouse of the No hassle and No colour influence on my sound. I f you are taking soundQ about a tuner it's a piece of crap.

Very dependeble! Used mine for little over 4 years now every weekend, pressed the mute switch over 3000 times ( I count*LOL* )and no fuzz! And I bought it used!

never needed it - dont know

Ive played all kinds og music in the 15 years I played - now I'm semipro and I would this agani in a heartbeat. I like the fact that's totally transperant soundwise and that it has a mute. Playing in cramped places I use a footswitch - works!!!

Very easy to use. Plenty of useful inputs front and back.
Great mute and included built in mic for acoustic tuning for many instruments besides my guitar.
Manual is small and easy to understand.

Excellent sound quality. I see other reviews stating when they ran preamped audio with distortion, etc. through it, they said it sounded terrible. It is NOT meant to be put into the signal chain after a guitar preamp with higher levels, etc. You run your instrument directly into it FIRST and then from the output you move on to the rest of your gear. It is flawless in my rack system.

It has not failed me yet.

I am sure they are fine. As this unit is reliable I have had no reason to call them as of yet.

I play all sorts of music from quiet to heavy and loud.
It performs well for me. Does not interfere with the rest of my setup and keeps me in tune throughout the gig!
Been playing for 20+ years and this is one of the better piecs of gear I have owned. If stolen I would replace it as I like this tuner very much. With the large display I can tune quickly when I need to.

Very easy to use! inputs in both the front and back and an output in the back. Pedaled mute option is a great idea.

Horrible. I tried everything to make it quite humming. Really bums me out. It sounds awesome for bass and clean guitar, but might as well give up if your using distortion. I am also a sound engineer and the level of noise is completely unacceptable for playing.

Only had it a week

Do not use it unless you are a bassist. Distortion is the worst thing for this unit. I run a PRS into a Mesa Rectifier and never have I had a unit produce so much noise.

Very easy to use. Nothing complicted.

Terrible. A lot of noise. This is the only rack effect I've bought which makes this much noise. It's unacceptable.

I've only used a couple times,so I don't know.

I haven't dealt with them ,YET. So,I don't know. But I'll call them to yell tomorrow because this tuner is a piece of crap and I paid $180!!

If you play loud music,don't buy this tuner !! It's unbelievably noisy. In fact,I've never bought an effect this noisy. I bought it on the internet,so I have to pay the shipping to return this junk.It sucks.

Cant' be any more simple. It's a tuner thast really easy to use.

I use it with my Fender Jazz Bass 5-string which i run through my Carvin Pro Bass 500 head running through a 4x10 cab and an 18" cab. Sound quality is great, doesn't affect it a bit.

Never had a problem with it. I gig alot and has worked flawless everytime.

Never dealt with them.

I give it a 10. I play punk/ska and it works great. Especially for those drop D songs, where I can tmute, tune and unmute within seconds.

It's a tuner. Couldn't be simpler. There are inputs on the front and back and an output on the back. There is a mute button for silent tuning, and footswitch jacks if you want to be able to remotely mute the signal (footswitch not included). There is also a calibration button in case you manually want to set your center frequency, but I never use it.

I run my guitar into my preamp, the the tuner in my rack, and then through my other effects. Seems like a silent pass through. No effect on the sound, which is what I want.

It seems solid enough. Durable metal housing. Also, it's in my rack case, so it's not going to take any beatings.

Never dealt with Korg.

Overall, I'd say that if you're looking for a simple rackmount tuner for guitar or bass, this is the place to go. It is very accurate and the LED's are bright and easy to see in the dark. Just tune until you see green. It's not the most interesting piece of gear, but if everyone had one of these, there would be no more "oops i'm tuned halfway between E and E flat" episodes at rehearsals or worse, actual gigs. Get one and make sure everyone else in your band has one too.

Very easy to use, minimum number of sockets switches etc, so its difficult to mis-configure. Locks quickly onto notes, even low B on my 5 string basses and the big LEDs means its easy to see the exact tuning.

The fixed power cord was hassle for me with rack mounting, so I fitted an IEC power connector. This wasn't difficult and took about 15 minutes all up.

I'm using the DTR-2 in the effects loop of an SWR Studio 220 amp. This allow me to use the MUTE fuction on the DTR for tuning as well as whenever I just want everything quiet for any reason. The DTR is quiet and there is no audible difference between it being on or off. When the DTR-2 is switched off, it defaults to pass through mode.

Very dependable.

I haven't had to deal with KORG over the DTR-2 but have had execellent support from them previuoulsy over getting a part for a DT-3 hand held tuner.

I also have an earlier Korg DT-1 Pro rack tuner which was equally as functional but tricker to use, as it has a bunch of different modes and it doesn't "wake up" in a ready-to-tune mode, like the DT-1 hand held tuner on which it was based.

The DTR-2 is a just a simpler tuners with fewer options, but comes up ready-to-tune and is simpler to use.... I like it more than the DT-1 Pro rack tuner.

The unit was extremely easy to use, very straight forward.

I was running from my Gibson Flying V to the DTR-2 and then on to my amp. (All my effects are in effects loops on my Marshall TSL JCM2000 head). The DTR-2 was extremely noisy. I talked around town to local music dealers and they said not to run "through" the DTR-2 but to purchase a "Y" cable. The idea was to run a cable from my guitar into the "Y" cable...one end of the "Y" to go to the tuner and the other end to go to my amp input....this would enable me to not go through the DTR-2, but merely "tap" off my guitar signal going to my amp. The DTR-2unit still produced unacceptable levels of noise. I figured the unit may have been defective so I returned it and got another one. The new unit performed exactly the same with excessive noise so I returned it and got my money back. Very noisy unit.

Only owned it about a week.

Never used.

I play Heavy Metal and have extensive effects and Rocktron Hush/Guitar Silencers and know how to use them. It just doesn't make sense to spend $300 on a Hush and then have a $200 tuner quadruple the noise on your system. Anyone who is even remotely noise sensitive better think twice before buying this unit.

This rackmount tuner has 1/4" inputs on the front and back and an output on the rear. Just plug in and tune. Works straight from active and passive instruments, in effects loops of amps, etc.
Picks up the note fast and, with a large display, is very accurate. There are many LEDs behing the display that smoothly show your tuning in cents. There is a separate "MUTE" light to show when you are muted (I put LEDs on my footswitch to show me). Has a mute button on the front with 1/4" jack connectors on the front and rear for footswitch muting.
The manual covers all of its functions nicely. Has a reference calibration feature that seems simple enough, but I have never used it.

Being a tuner, it doesn't actually affect the sound. I run my old passive bass through the tuner and into my Carvin R600 bass amp. It picks up with no problem. I play loud through a 4X10 w/ tweeter and 15" cabs and haven't heard noise, hiss, etc. I have a picky ear, but can hear no artifacts.
I don't know if it buffers the signal. The metal body seems to keep all stray radio frequencies from creeping in.

I've owned mine for more than a year and have had no problems. It has been in my four space rack right above my amp the whole time. The mute function uses a relay (you can hear a slight click), but always works without problems (it works with any on-off switch). The jacks are tough enough to take some pulls on the cable. I trust it to work every time.
It has a built in power supply with attatched 120V power cable that is about 4-5 feet long.

Haven't had to deal with problems, so I don't know.

One of the things I like most is its sleek look. The natural aluminum and black plastic display are nice to look at.
I've been playing bass for about 3.5 years and expect to use this tuner for a long time. It has a wide tuning range to cover many kind of instruments. I'm sure it works with every style of music and with most equipment setups.
I tried the new BOSS TU-2 stage tuner; it is great too, but I preferred the rackmount. It's worth the extra $50 to me. I'm not sure which one I'd buy again if I lost this one, though. If you want more features, check out the DTR-1.
It is simple, efficient, versatile, and good at what it is made for. I never have to worry about it. It's only about 4" deep and light weight, which is good for a rack full of other stuff. All of these reasons make it worth the $150 to me.
