The “Harrison Ford” Filters (no relation to the star of The Fugitive) are a clone of the sweepable EQ filters from vintage Harrison consoles. The PCBs are very compact (eight fit in a 1RU case), use only modern components, and run on +/-15vDC power rails. The PCBs were developed by GroupDIY members Jens, 12afael, and Marcocet. A custom case and front panel from Collective Cases accommodates eight filter channels with inputs and outputs via DB25 connectors.
