OVERVIEW

One of the world's top-selling stage tuners, the BOSS TU-2, has evolved and improved into the TU-3 pedal tuner. Housed in a tank-tough BOSS stompbox body, the TU-3 chromatic tuner features a smooth 21-segment LED meter with a High-Brightness mode that cuts through the harshest outdoor glare. Choose between Chromatic or Guitar/Bass tuning modes. Accu-Pitch Sign gives you pinpoint visual verification that tuning is complete. The BOSS TU-3 tuner incorporates a convenient Note Name Indicator that can display notes of 7-string guitars and 6-string basses, while the Flat-Tuning mode can support up to 6 half-steps. It's the kind of instrument pedal tuner that no performing guitarist or bass player should be without.

Provides easy-to-read tuning with a display made to be visible in dark or bright conditions.

FEATURES
  • 21-segment LED meter with brightness control
  • High-Brightness mode enhances meter visibility outdoors
  • Accu-Pitch Sign function provides visual verification when tuning is complete
  • Chromatic and Guitar/Bass mode (tune by string number, with support for 7-string guitars and 6-string basses)
  • Flat tuning is supported with Guitar Flat mode, which allows for drop tunings up to 6 semitones below standard pitch
  • Signal is automatically muted when the tuner is on
  • Supplies power for up to 7 BOSS compact effect pedals (with optional PCS-20A Cable)
  • Accessories:
  • Owner's Manual
  • Leaflet ("USING THE UNIT SAFELY," "IMPORTANT NOTES," and "Information")

Get in tune, quick, easy, and accurately with the BOSS pedal tuner. Order one today.

          Comments about Boss TU-3 Chromatic Pedal Tuner:

          I have had these since they came out with the TU2. I think I have worn out 3-4 of them over the years! ALWAYS need a tuner onstage, and this one is practical. I wish Boss would but an on/off mini switch for the aweful tone sucking buffer, though. (I wish Boss would do this with ALL of their otherwise excellent pedals!) I bypass my TU3 with a small loopswitcher that is velcro'd on top of it. The mute and brighter LEDs are nice features.

            Comments about Boss TU-3 Chromatic Pedal Tuner:

            I LOVE this pedal! I had been a longtime user of the Boss TU-2, this pedal's predecessor. My TU-2 has gotten me through hundreds of club gigs over more than 10 years of use, and it's still fully functional, albeit with chipped paint and signs of heavy use. But I recently played an outdoor gig in bright, harsh sunlight, and the old TU-2 was hard to read in the glare. So I looked around and found this TU-3 on MF. I love the TU-3. It is virtually the same as the TU-2, but with two improvements: you can select a brighter LED display (to fight the harsh sunlight), and the tuning is even more accurate, with a better display. I go down to Drop D on my 4 string bass a lot (several times a gig), and this pedal does it faster and more accurately than the old TU-2. Five stars, this is the best piece of equipment I own, I love it.

                Good tuner. What else can you say. Its tough, durable and you can tune silently and quickly. If you want a highly accurate strobe tuner then shell out the coin for one. Don't expect that type of accuracy in a stomp box. So for my review I won't compare it to tuners that cost 5X the price. For a stomp box/pedal board tuner, this one works fantastic.

                    My jack finally went bad on my old tuner. I noticed alot of musicians use this BOSS tuner so I decided to give it a try. It is built very solid, very easy to see and use, and even has settings for 1/2 step and multiple guitars. Very glad I spent the cash to get a nice tuner!
