Korg DTR-2

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.
