FWIW saw one for sale online less than usual due to problems (namely worn rubber stoppers under the front side of the treadle keeping the wah activated all the time unless treadle deliberately pressed back). Might be something to watch out for. The strength of the instantaneous noiseless switching (and how it's physically accomplished) possibly becoming a problem depending on conditions.

Yeah worn stoppers could cause the same problems I was seeing but an easy fix.
Still prefer to be able to set the treadle where I want it plus I like hear & feel the crunch :twisted: of a good ol stomp switch...

the Castledine one (sound) I think plugs into some old solid state Vox amp with some sort of fuzz or tone altering circuit, so wonder how much of the sound is from that

Yeah would be nice to hear clean then mean. BTW both McConachie & Castledine offer custom pots,I have the Castledine ICAR in the wah I rebuilt & like it, haven't tried the McCon-O-Pot yet..

check out some interesting posts by Matt Syson on issues with gain pots (for mic pres in this case) :

http://www.gearslutz.com/board/geekslut ... inger.html

(I don't know for sure, but) if there is an analogous situation for wah pots (i.e. small R changes that are difficult to screen on the pot track accurately), I suppose it would give an explanation for any difficulty making desired tapers (expense, difficulty, low yields or whatever exactly goes on).

Interesting, yes I think it pertains for sure. I can't explain why certain pots can sound so different in a wah but I believe there's more to it than the taper, some of the replicas seem pretty close in that regard. Could it be the composition of the resistive element & could the center wiper play a role? dunno..

Built in fuzz, what a concept. Check out the wiring in the Klemt, those Siemen's EL34's look very Mullard like, yep I see an xf something :wink:

the glass looks nice on Mullards (for whatever reason). (Well, the general aesthetics look pleasing on Mullard GZ34 and other ones I have or have seen. Wonder if there was some actual intent to make them look nice or if that was just how they came out. Or maybe just in my head. :oops: :lol: )

p.s. the guy is apparently a race car mechanic 8)

Yes Mullard glass looks very nice, awfully nice of him saving all those old sets destined for the dump 8)

Hey wasn't this a wah thread? :lol:
