Boss TU-3 Chromatic Tuner Pedal

The world's top-selling stage tuner, the BOSS TU-2, evolves and improves with the debut of the TU-3. Housed in a tank-tough BOSS stompbox body, the TU-3 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, and enjoy visual pinpoint tuning verification with the Accu-Pitch Sign function. The TU-3 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 six half-steps. It's the standard tuner that no guitarist or bass player should be without.

"Cost effective 'road worthy' tuner"

Overall a 9 - again, hate the adapter, but this product itself is worth every penny.

Sound
I've used this for both the bass and guitar in live settings and it's done everything I could want it to do. If you take the time to learn how to switch the modes, there are no issues at all. I love the mute/gate when it is engaged as I do some bass playing for religious services and it is a great to be able to tune/adjust quickly on the fly. The LED lights are nice and bright and visible when the stage lighting is bright. Additionally, I've found the accuracy of the tuning to be spot on.

Features
Most useful features described above. However, if you're going to use it alot, get a power adapter. This thing loves batteries. But DON'T buy the Boss one. I bought the "one spot" adapter and it has held up far better with no issues. Didn't give it a 10 due to the adaptor Boss has and the fact that it loves batteries.

Ease of Use
I read manuals unlike most people. So if you read the manual, it is SIMPLE to use. I browsed through the little manual in the box and had it up and running for both guitar and bass and can now change it on the fly.

Quality
Boss - always has rugged dependable stuff. Their adapters suck though. Get a 'One Spot'.

Value
I have a Korg rack tuner for bigger gigs, and I use this for smaller ones. Well read more worth the money for the smaller gigs but could be used for large ones as well it that's your preference.

Manufacturer Support
Never have needed support of any kind. Says alot about their products if you ask me.

The Wow Factor
I've always been partial to the simplicity/look of MXR boxes as the Boss boxes are a bit bigger. But I have no issues with this one at all. It has already received its share of nicks and bumps from consistant setup and tear down - that makes it "prettier" in my opinion.
