tunable wah

[jason h]

Does anyone know of a layout for a tunable wah. Something LIKE the RMC3. NOT the RMC3 itself, just something along that line.

thanks

I have made a layout PCB which is posted at GGG

I found the layout a great way to experiment with the Vox-wahcircuit and have used it to make a board with the values I like. Nowadays I use only one inductor (made by Stuart Castledine, check his site for very good inductors), a Teese pot and Allen Bradley Carbon comps for the vintage mojo  :lol: . Like Teese I use BC 109 transistors.

Is this project hosted any place currently? it seems to have to gone from the GGG site.

Correction on further investigation, JD, Sleep founder of GGG, has modified Gerben's design and it is still available as a wah project on the GGG site. I won't link to it as it's a fully commercial outfit these days (well I'm behind the times, it has been this way for a number of years).

I remember this, tuneable wahs, being a hot topic after its implementation in the pioneering Teese rmc3 wah.
