Mick	Re: Wanted good wah Mods and inductor manufacturers Basically, If you look at the top spec very expensive wahs, then it appears that they replace many of the fixed resistors in this simple circuit, with either internal trimpots or external full size pots, they also switch in other capacitors instead of the standard reswonator 0.01uf cap. Then a couple of them double up on the inductor. What I was after was some guidelines on the trimpot/ cap values etc. to use from people with the bought jobs. Failing this I intend to replace the resistors with trimpots as follows, e.g. 68K with 100K linear and so on. To upgrade your wah, you need to make a PCB. When /If get the information from wherever, (anybody). I intend to put the layout etc. on the net. so other people can try it.
