Features and Controls

Sensitivity: Controls input sensitivity to match the ouput of the guitar's pickup. Set this volume low for high gain active pickups. The guitar signal and RCP660's input signal come to the same level when this volume is turned fully clockwise.

Attack: Controls pick attack intensity. Turn this volume clockwise to emphasize the attack and turn it counterclockwise for lesser and smoother attack.

Sustain: Controls the duration of a picked signal at a constant level, before the note starts to fade. Turn it clockwise for more compression. Set it slightly low to use this effect as a limiter.

Master: Controls effected output volume. Turn it clockwise for more volume.

Effect On/Off, Effect LED
