Buchla 291 vari-bandwidth bandpass filter
This module is based on the Buchla 291 vari-bandwidth bandpass filter, tho it uses the blackbox rather than vactrols. The CV sections have been changed from the original circuit to a simpler version, it also has a Q pot, LP and HP outputs.
Assembled modules are built to order. They will be ready to ship within 1 week of ordering, usually I manage it in 1-2 days.
