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|
|Q1||? (medium gain silicon NPN)||MPSA18|
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 😉
