Wah Layout

[rocket88]

i'm sure i'm not the only person that has either an empty wah pedal, or broken wah that could use some rebuilding. i found this posted by R.G. Keen that has a generic schematic for the most common wahs, with the values for each wah. this got me thinking, someone could make a single layout that can be used as a template for each wah and you can build anything from the vox grey to rare boomerang, and colorsound wahs. i tried making a layout but the location of the inductor kept messing me up, and the layout looked like crap.



as a side note, i did a lot of searching and found a layout for a grey by sinner (turretboard.org), but i can't get it to work, i just get a squealing volume pedal. i traced the layout and compared it to the schematic, it looks good, but can't figure out the issue.

even though the inductor throws me off, i took a shot at it. need someone to take a look at it to check that it matches the schematic properly.

V1 - Halo Style Inductor


V2 - El Rad Style Inductor

Here's the full article for those interested, it's really quite good.

i can't agree more. that's where i got the schematic.
