BOSS TU-88BK guitar tuner&monitor;

Small, cool and feature-packed, BOSS' TU-88 is a must-have for guitar and bass players on the go. It provides needle-accurate tuning, a metronome, and a headphone amp with speaker simulator for monitoring effects, including compact pedals. 



It has three tuning modes: chromatic, guitar, and bass, Flat Tuning function, and ACCU-PITCH verification with an audible beep. It has a built-in headphone amp that lets you tune, jam, and play your effects with headphones or direct recording. It also has a built-in metronome with selectable rhythmic patterns and volume control. The MIX IN feature allows jamming with an external music-playback device such as an MP3 player.
