OVERVIEW

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

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.

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.

Very accurate, I can tune my 5 strings bass down to a low "A" easily. For a low "G" it barely detects the frequency, but still useful.
It has two outputs (bypass and output), the second one mutes your sound while tuning your guitar/bass, this is pretty useful also if you want to switch your guitar/bass between songs without turning off your amp. No messy sounds.
I recommend to use the power cable instead of batteries, otherwise you will not be able to finish your concert when the batteries are already drain. One 9v battery is included, the power cable is not included (to bad from boss for such an expensive pedal. I use "One Spot" cable for my TU-3). The battery is pretty easy to replace, no tools needed.
Very strong metal case and rubber bottom for improved traction.
This TU-3 is more accurate than my boss TU-12 (which cannot even detect the low B frequency) and the onboard tuner of my Orange 100BXT amp. I uploaded a comparison to youtube if you wanna watch.
TU-3 is somehow costly, but i strongly recommend saving some money until you can buy this one (for its quality and precision).

Didn't meet my needs/style.

I'm sure it works well for many people but for me I could ear-tune faster. Unfortunately the return policy is restrictive so I guess I'll keep it and sell it on Craigs.

Comments about Boss TU-3 Chromatic Pedal Tuner:

I've been using a tuner off my amp and would have to turn down, tune, turn up every time. Should have got this years ago. Works great on my bass. It's so easy that i tune up way more often now.

      Could not tune up with a clip on tuner while the others are still playing, too much vibration in the room, this solves that problem.

        Comments about Boss TU-3 Chromatic Pedal Tuner:

        This is the tuner pedal that covers all bases. It just works, and sometimes that's just what you need from a piece of gear. The brightness switch is great, the pedal is accurate, and its string/chromatic selector, along with the detuning flexibility leaves no reason not to own this.
        I use it for Bass primarily, and its great knowing that I could bring this to ANY gig situation from pop to metal, bass to guitar.
        One pedal, a Hundred different gigs, rock solid and accurate.

                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.
