BOSSTU-3 Chromatic Floor Tuner for Guitar and Bass | Industry-Standard Performance | Tank-Tough BOSS Stompbox Body | 21-Segment LED Meter | Accurate to +/- One Cent | Accu-Pitch Sign Function

It’s a tuner. It’s a boss. What could go wrong? This thing is great, works well, easy to use, very intuitive and easy to read. I’ve been waiting to buy a pedal tuner for some time now to replace the clip on tuners (though they still have their place) and finally decided on this especially with a recent sale. Great item, I expect it to last a long time like my other boss pedals.

I like this pedal, makes life a lot more easier/reliable to see intonation and tuning. Thank you Boss.

Solid build. Got at a nice sale price. Expect it to last.

When I'm playing at home, I play with a Peavey Vypyr amp. Those amps have terrible tuners. Never seems to pick up the correct note on my guitar. This tuner is much better. Easy configuration, you can set it for guitar or chomatic or flat steps down, etc. The interface is super easy to read. I personally like the style where it looks like the LEDs are spinning right/left for sharp/flat, but they have the standard off from center tuning that most tuners use. All in all, this is a great tuner pedal, and I'm very happy with it. It does what it does very well.The thing I really like about this tuner is that there is an output and a bypass. Output gets cut when the pedal is active. If you are playing live, this is the one you will want to use. Bypass never gets cut. It's great for at home or if you are tuning somebody else to your instrument. But there's another awesome use for it; you can use it as a splitter and run your signal through 2 amps. This is fantastic for recording. Setting one amp up for the low end and another amp up for the high end and then mixing them together in the studio software makes for a very full sounding recording. If you want to run the same effects, put the tuner last, if you want to run different effects, put the tuner first.

This is an awesome tuner with lots of cool additional features for all kinds of tuning capabilities. Nice bright display is easy to see and the floor pedal format is great. You can also power other pedals through this unit if you get the A/C power supply. I use mine with 9Volt and very happy with performance. I do a lot of open tunings so a must have for live performances. Very happy with purchase.

First of all, consider how you want to power it before purchasing.It comes with a 9 volt battery which they say is not for heavy duty use and therefor not made to last long.One reviewer said it eats batteries.Within 2 weeks of light usage the battery died unexpectedly when I went to use it.I considered getting replacement batteries but decided to purchase the Boss power adapter and not have to worry about the battery dying.Secondly, I was playing a gig immediately after tuning my electric bass. One of the band members told me my E string sounded out of tune. I showed him with the tuner that it showed it was in tune.At home I decided to compare the tuning using the pedal tuner with my tuning app.I discovered the tuning was the same, EXCEPT the tuning app registered my E string as a half step different than the pedal tuner. I trust the tuner app and also checked the tuning manually to confirm.A Google search found other musicians having the same issues with the pedal tuner. The solution I discovered was to do a reset of the pedal tuner which resolved the issue, but I will be checking the tuning periodically against other methods to confirm it is working properly.I played upright bass for 30 years before electronic tuning was popular. I had to tune by ear.My advice is to use the electronic tuners but also learn to listen for accuracy of pitches and trust your gut if something doesn't sound right.

Imo its the best tuner out there for any pedalboard atm, a bit pricey though

Perfect tuning gear for on stage performance
