Hello fellas, i've decided to make some contribution to this forum, and i made a layout for sabrotone's Mark IV emulator, it's NOT VERİFİED, i'm not an expert with drawing layouts. Let's make this layout work :) All the schematic work and vero layout from sabrotone.com. I'm just trying to add something to his great job :applause:

Note: You need Sprint Layout 6 drawing program to view and edit it.

C16 is unnecessary - leave it out or just increase C25 to 560p :wink:

On your Sprint layout C22/500p is shorted... Should go to the other side of the trimpot. :wink:

C28 positive lead is connected to the negative lead of C26, - C26+ and C28+ should be connected

İ think it's correct now, thanks for the information :)

Version 0.2 of the pcb and layout :) Edit: İ put the wrong layout, now it's correct one.

R1 (1Meg) on the input seems to be missing?

i did't put that on purpose, i don't need that "pull-down" resistor to eliminate pops, i use that resistor on my switch board :) you can add it if you want :)
