Boss TU-3S Chromatic Pedal Tuner

The TU-3S is the same in every way to the TU-3, except scaled down by removing the footswitch to save you space on your pedal board. As with the TU-3, the TU-3S features a smooth 21-segment LED meter with a High-Brightness mode that cuts through the harshest outdoor glare. Enclosed in a steel road ready housing. Chromatic or Guitar/Bass tuning modes, Accu-Pitch Sign function. The TU-3S incorporates a convenient Note Name Indicator that can display notes of 7-string guitars and 6-string basses, while the Flat-Tuning mode can support up to six half-steps.
