CMOS Bass Overdrive
Controls (Front)
Level
: Sets the volume of the overdriven
signal.
Drive
: Sets the amount of saturation in
the overdriven signal.
Controls (Back)
Open the magnetic bottom lid to access
the controls.
Blend
: Mixes the clean input signal with
the overdriven signal. The clean signal is
fixed at unity gain, while the volume of
the overdriven signal is set by the Level
knob, allowing for fine control of the
blend ratio. Turn clockwise to blend in
the clean signal.
Tone
: Controls the high frequency
content of the sound. A variable low pass
filter from 3 kHz to 8 kHz. Turn CCW for a
brighter sound.

Grunt
: Provides a low-end boost to massively thicken your sound when
engaged.
MBoost
: Gives a subtle 6 dB boost from 300 Hz to 1 kHz to help you cut
through the mix.
