ANALOG BASS DRUM

Manual v1.0

Inspired by Craig ANDERTON's (1983) diagram of Hip Bass Drum, this reinterpreted analog kick for
the eurorack format delivers powerful sound and many possibility with its many controls.
The idea of the original schematic was to get as close as possible to an acoustic drum kick. I chose
to widen even more the sound palette to get kicks typed 808, or more felted, rounder etc ... here is
the Analog Bass Drum (ABD).

It is recommended to lower the output volume before any connection ;-)

Connecting the ribbon cable

! Be careful to always respect the connection direction of the tablecloth: by convention, the colored
part (usually red / pink) of the ribbon represent 

-12V

 !

Note : on all PCB 

, the -12V « red line » is screen printed near the power connector.
