As an "Extended-Range" bassist I've had to be very careful in my tuner purchases, making sure they can not only read and properly tune a low B-string on a 5-string bass (or even lower when drop-tuned to A or even the low F# of a "Sub-Contrabass" tuned to F#BEAD) as well as the high C-string of a 6-string bass or a 5-string strung EADGC as I use for the ability to the high-range parts of a 6er while being much more comfortable playing 5-strings. My tuner for over a decade was an mid-90's Korg BT-2 bass-specific tuner that did a wonderful job in spot-on tuning in both areas but was housed in plastic and not strong enough to use as a pedalboard-mounted tuner (it still lives on doing a wonderful job as my "Practice Area" tuner).

When revamping my Pedalboard a few years ago and realizing that it was time to try out new tuners, the Korg DT-10 "Mark I" (the Silver bare metal original model as opposed to the Black-colored revisions) was the first on the list and quickly ended up as the front-runner and eventual winner. The combination of ease-of-use (step on it to turn it on and start tuning until the analog needle-like LED display centers... or simply start tuning if you're like me and have your pedal fed by a side-chain signal and not in-line with your signal - much easier to tune "on the fly" that way). The display is accurate and quite easy to see and understand: besides the LED display that shows in cents how far off you are as well as small arrows for a subtle visual cue in which way to tune, you also have the inputted note in a nice large area, a medium-sized dot to indicate sharp notes, and another dot that indicates "Flat Tuning", a mode that automatically drops the tuner to Eb, Ab,... tuning that many rock bands often do to sounds a bit heavier without moving to lower "Drop Tunings" and to give Vocalists more range. In my opinion it's the perfect amount of information to give the on-stage player without overloading them with various pieces of info, something that a good deal of tuners do which relegates them to home usage but not live. The rear connections are follow the same concept, giving you 1/4" Input, Output & Bypass jacks to use as well as the controls for the "Flat Tuning" mode and a Calibration Button if you don't tune to A440 and want to set the tuner your personal Standard Tuning... useful for Middle Eastern, Asian and non-Western styles of music, and finally your standard 9V power supply input.

Having owned the DT-10 for quite a few years now I'm perfectly comfortable with it and see no reason to "upgrade" to a newer model. Besides the slight decrees in size they don't do anything that I feel I would need without jumping to the next price level ($150 and upwards) and some feel downright cheaper underfoot, a very important fact for a pedalboard-mounted tuner. The DT-10 has been an important part of my pedalboard setup since I purchased, and should theft or breakage happen I'd likely purchase a used model as opposed to a newer tuner. "Newer" doesn't always mean "better".

I love this thing. I've been using this tuner for guitar and (mostly) bass for about 6 or so months now. We tune a half step down, so the flat tuning feature was necessary. The mute feature is great, the tuner is easy to see onstage, and I have only had to replace the battery once or twice. This is one of the few "must haves" in my gear bag.

I got this pedal for my Ibanez 5 string bass and let me tell you this thing has amazingly low range. I wasn't expecting it to pick up my B string very well but it reads it flawlessly. This pedal is also very sturdy and heavy built. Buy it and you wont regret it.

This is a wonderful tuner. Its an essential tool for any serious live musician. Sure the price is high, but believe me it's worth every penny. Also its built tough and is ultra precise. This is a jem!!!

I've had this pedal since january '04. it's held up really well and tunes great. I use it with a digitech ex7 and boss sd1 and dd6. Tone intact :), even when using the non-bypass option (mutes while i'm tuning and I've comapred it with bypass......tone sounds good). It holds up well to my size 16 feet, and runs well off of batteries (though I prefer to use my dc brick). Get it.
