hey guys,
I am looking for the Dunlop 535Q wah schematic. If you have one, can you let me know please.

Thanks,
Duke

I dont know if that would help any..I have one and the inside is all mini-circuitry..ect..and i think its double sided. From those ive known w problems--incl my own-- about the only real diy fixes include the pot/ and maybe inductor...Good luck anyways..It would be insane to try to clone one of those= from what i can tell looking at it. I hate when they (big companies) make thier boards/components like that. --small--

You, or your friend, should build the Mod Wah from GGG (www.generalguitargadgets.com). I just built it into my vox wah shell that I gutted for this project. It is excellent, and I think it does most of what the 535Q does, at least functionally.

Esp- i bought the same board and plan on doing the one w the 2 inductors-6 way cap switch ect... the whole works..Which one did you do?

Well.. he asked if i knew where to get the schematic and I said I'll try to help him. What does he want to do with it?? I have no idea.

Another thing to keep in mind is there is more than one version of the 535Q. Among other things, the original ran with two 9 volts - not sure if it was bipolar or +18v. The one I have uses a single 9v. I'm pretty sure there are other differences (bypass?) and possibly more than two versions?

I'm doing an LDR/CV mod to a 535Q and could also benefit from the schematic. Mine is the 18 Vdc version.

jimbob, I'm doing the works. Well, sort of. Due to cost of certain parts (fulltone inductor, and hot potz II), I planned for this to be a two stage project. So stage one was to build the complete project minus those parts. I have the 3Pol3Pos rotary inductor switch installed, along side the SP6Pos, and ready for soldering once I can justify the $$ for the aforementioned ridiculously priced parts.

In the end I will end up with a gutted Vox 847 enclosure that contains a fully tuneable GGG Mod Wah with a pulsing blue on/off indicator LED, and either true bypass or wah/volume switching- I'm undecided on this.

Good luck with your Mod Wah. Let me know how it goes!
