Review: Great tuner! - I had been using a Polytune, then started having some problems with it, so I got this as a replacement and really like it better than the Polytune, mainly because it gives you a much more precise reading, even down to cents as opposed to so many tuners that will tell you the string is in tune as long as the intonation is within an acceptable range of tolerance. So if one string is a little sharp, and the next string is a little flat, you got a problem! This tuner is sort of like an analog style that really lets you know where you're at. It is very silent, no click when you hit it. However, unlike the Polytune, you just hit one string at a time, which works for me. How can you go wrong with Boss?
Review: Double duty pedal, tuner and a splitter - 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.

## Questions & Answers

**Q: can this tune a saxophone??**
A: Saxophones absolutely need to be tuned every time you take off the mouth piece or with temperature changes such as going from indoors to outdoors on a cold night (marching band).  Tuning is done by shortening or lengthening the distance an the neck of the sax by moving the mouthpiece in or out.  This tuner could be used to tune a saxophone if you have a cheap mic that has a 1/4".  That said there are less expensive tuners with built in mics that would better suit your purpose.  

Please note though that no matter what tuner you buy, if it is set to concert pitch (440Hz A / piano tuning) you will want to transpose the notes from Bb (tenor) or Eb (alto) to concert pitch when tuning your saxophone.  In other words when you play a C on a tenor saxophone it is a Bb in concert pitch.  For alto a C is an Eb in concert pitch.  There are some very expensive turners that you can change the tuning from concert pitch to other pitches but they are a waste of money since transposing is not difficult.  Make a chart or download one if you struggle at first.  Remember that your sax could be sharp on some notes and flat on others so check multiple notes and find the tuning where the most notes are in tune and those that are not are just a little sharp or a little flat.

**Q: How does the TU-3 effect a fuzz face if it's placed a couple pedals away after the fuzz ? I assume it has a buffer like most Boss pedals.**
A: It is buffered, but the buffer won't affect anything that comes before it. Since certain fuzzes don't "like" buffers, putting those before the tuner will work fine.

Guitar > Fuzz Face > Tuner ( or any buffered pedal) > Amp

**Q: Is this product adequte for a 10 string  pedal steel guitar ? I was told to get a tuner that shows the frequency and I do not see a # on the  display**
A: This won't show the frequency in Hertz, but it will indicate pitch, and the 10 string pedal steel should be in its range. There is a dot on the display to indicate a sharp.

**Q: Will this work when only plugging the input?**
A: Yes
