Pedale Accordeur ROCKBOARD +Detune ST-01

The RockBoard Stage Tuner ST-01 combines all aspects that musicians seek in a chromatic pedal tuner. Its large, bright, but not blinding LED 28 segment display provides an easily readable interface even from meters away. 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 4.168 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.
