Mad Professor Blueberry Bass Overdrive (pcb)

Mad Professor Blueberry Bass Overdrive (pcb)

Bjorn Juhl design

The Blueberry Bass Overdrive is designed to bring you the light to medium overdrive reminiscent of vintage tube bass amplifiers.

While mainly designed for bass guitar, the BBBO can also be used with other instruments for low, dynamically controlled distortion.

 

VOLUME: controls output.

DRIVE: sets the amount of distortion and sustain, as well as the type of distortion. lower settings give dynamically controlled overdrive, the unit distorts more the harder you strike the strings and there is no definite clipping point, but rather different shades of distortion as the amplitude changes. Higher settings will give more compressed sounds.

NATURE: is a tone control for filtering and to control what register distorts. Turning CCW gives more low-end and also distortion in the lower registers. Turning CW gives an emphasis in the upper midrange for more protruding solo bass tone.
