Triple-Function Tuner for Guitar and Bass

Small, cool, and feature-packed, BOSS’s new TU-88 is a must-have for guitar and bass players on the go. Available in black or white, it provides needle-accurate tuning, a metronome, and a headphone amp for private tuning, warm-ups, and effects verification.

  • - Three tuning modes (Chromatic, Guitar, Bass), Flat Tuning function, and ACCU-PITCH verification with an audible beep
  • - Built-in headphone amp lets you tune, warm up, and check your effects in private
  • - Built-in metronome with selectable rhythmic patterns and volume control
  • - MIX IN allows jamming with an external music-playback device (iPod, etc.)

Feature Packed

In addition to BOSS’s famous needle-accurate tuning, the TU-88 has lots of great extras onboard. A built-in metronome with selectable rhythms and tap-tempo is a great practice tool. The Mix Input lets you connect an iPod or other music-playback device for play along practice and jamming.

Private Monitoring

With the TU-88’s built-in headphone amp, you can plug in a set of headphones and tune in complete privacy. It’s also a great way to warm up before a show, and to verify your effects chain through headphones before letting loose through your amp.

Setup Example: Jam Along with Audio Players, PC/Mac
