For no apparent reason, here’s a vero layout for the Bespeco Weeper wah effect. I guess you could either set this up as a “fixed-wah” box or put it in a regular wah enclosure with foot-controlled pot.

Based on a schematic by Gottfried Divos, found here.


This effect apparently also go by a few other names with some slight modifications to the part values. I’ll see if I can add some more info on that tomorrow.

Update (23.06.2013): Substitutes you can make to create other similar effects:

Colorsound Wah-Wah Zvex Ooh-Wah
R2  330K 330K
R5  180K 180K
R7 180K 180K
R9 470 jumper

R12 same 470K

Update (02.09.2013): Verified as working, thanks to Clint C.

Update (12.09.2013): Not sure what I was getting at about a cut underneath R10. No cut necessary and layout has been updated. Thanks To Olav for spotting this 😉

  1. Hi Harald, is this schematic supposed to have a wah pot? And change to an LDR in the Zvex oohwah?
