The true bypass does not affect your guitar's tone at all and its two outputs allow for either silent or audible tuning. The ST-01's reference frequency can be changed in 1 Hz steps from 432 to 445 Hz with a tuning range from 27,5 Hz (A0) to 4.186 kHz (C8) accuratly down to 1 Cent. It also feature a handy detuning function, which lets you drop your tuning by 1, 2 or 3 semi-tones. All this, combined with the StageTuner ST-01's compact metal housing makes it the optimal companion you will not want to miss on your (RockBoard) pedalboard.
