Title: DOD FX72 Bass Stereo Flanger Reverse engineering
Post by: loki on April 21, 2004, 01:34:07 PM
Hi guys, i just happen to own the aforementioned pedal, today i opened it up because i decided to spray-paint its enclosure (that shit-like brown is horrible  :P) so i took a look at the PCB, it was a cool thing, since it's the first time since i became interested in stompboxes DIY that i had a look to a real one understanding some of its parts.
Anyway i was wondering if anybody would be interested in getting a schematic and layout from the PCB, since i think i've not seen it around... so i could try to do it myself (not recommended i'm much of a newbie) or post some high res pics so that someone more expert can reverse enginner it, with me helping with some parts readings....
let me know
bye!

no actually it uses a Motorola MC14007

The MC14007 is used for the bypass switching. The delay line will probably be an 8 pin chip with a number like MN3207. There also may be a clock generator chip with a number like MN3101.

Take care,

neither of the two things, i just wanted to know if anyone was interested in getting a schematic out of the PCB, but since there is the schem already around i guess it's pointless, i can mount it back  :P
