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!

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.

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
