  • Boss TU-3

    The only tuner that matters. Perfect for any guitarist/bassist. If you’re thinking about this or the polytune...get the TU-3. You won’t regret it!

  • Simple, accurate, sturdy...what more do you need?

    Accurate tuning. Many modes let you tune by note or string number for guitar or bass. The output and bypass options are nice depending on whether you want to use it as a kill switch. Also like that it has it's own 9v out, so you can chain it to another low-gain pedal.

  • Close enough for rock. Good buffer.

    Not as accurate as the TC PolyTune in my opinion but is close enough for rock and functions good. Also, like all boss pedals the buffer is good. I really like the buffers in boss pedals when you use 1 or a couple boss pedals and all other true bypass pedals.

    Well... it's a tuner! Moderately easy to read. Can't really say much more... it's a tuner, either it works or it don't!

  • Bulletproof, does the job

    I used a TU-2 on live gigs for years with no problems. This thing seems even faster and more accurate/easier to read, but still has the same sturdy boss build quality and great buffer.
