DOD - FX20B Stereo Phaser Schematic

Postby Gino » 12 Jan 2009, 03:35

Hey, first post here. I'm a member at BYOC and DIYstompboxes. Alright, I'll get right to it... Anyone know where I can find the schematic for the DOD FX20B Stereo Phaser? I found the schematic for the FX20C but I don't know if it's the same as the FX20B. Does anyone have any insight? Thanks in advance! :)

DOD - FX20B Stereo Phaser  [schematic]

I asked Digitech for the schematic of the DOD FX-20 (4-stage OTA, mono), but they didn't have the document. But they did send me the schematic, layout, and trace images for the DOD-FX20B, which is a 6-stage OTA stereo phaser.

And they responded in just 13 hours! :applause:

Document attached. It's factory document, but there are no copyright notices and they didn't mention not sharing..... :mrgreen:
