Hello everyone, since I´ve built a biphase with great results people have asked me to make extra sets of the pcb´s available, since that´s the biggest obstacle for most. A set costs 60 euros/70 dollars without holes, 80 euros/92 dollars pre-drilled(time and drills, it´s a lot of holes!).
Made following the exact same schematics as for the original 70´s biphase, with the exception of the added rate-LEDs to see each phaser´s rate and depth at a glance. The control PCB has been redrawn to half of its original size(from 300x200mm to 150x200 mm) for easy accomodation in a footbased pedal or a rack unit(I use a 1u rack).
The effect works 100% like the original:
- controls for each phaser
- controls for the sweep generators
- phasers on/off by any standard latching double footswitch
- sweep/rate pedalcontrol using a standard Roland EV-5 expression pedal or M-Audio EX-P
Sold including all schematics, layouts, manual and a list of all components, and with indefinite help and problemsolving.
