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.

Indicates the
preamp is in tube overdrive mode.

Switches all of the BASSBASE 400’s outputs
except for the TUNER OUT off. Use this button for

to indicate the amp is muted.

Use this jack to send signals to a
mixing console or additional power amp.
