TUBE SATURATION LED: Indicates the preamp is in tube overdrive mode.

CLIP LED: Indicates all types of clipping in the BASSBASE’s preamp (including post-EQ section and FX loop distortion). In other words, an illuminated CLIP LED does not necessarily mean the GAIN control is set too high, it may also indicate the FX signal level is not adjusted properly.

MUTE: Switches all of the BASSBASE 400’s outputs except for the TUNER OUT off. Use this button for breaks between sets, switching instruments, or when tuning. The RED MUTE LED will illuminate to indicate the amp is muted.
