I don't mean to hijack the thread in anyway but my experience with those shells was different.
I had tried the same thing with a Carvin wah shell awhile ago.
I believe the Carvin and the Sam Ash wah shells are Chineese knockoffs of the Dunlop Patented shell.
I tend to be overly critical of things but found the gears to not feel quite right on my chrome wah.
In my opinion even the cheapest used Dunlop is much better quality wise and thus has a smoother feel to them.
Of course I have been into wahs for 35 years or so now so you can take it as you like.
That being said I ended up using mine for a Leslie speed foot controller.
Hey Nero1985,
First off thanks for sharing your project with us all. The blue LED looks killer as does your use of pots to tweak the circuit on the fly.

Just curious, is that Blue LED on the rocker pedal itself?
If so, how do you keep it secured and keep the wires from breaking? I couldn't tell from the inside pics.
Also, what value caps do you have on the selector?
I ended up putting my wah project into a Teese shell.
I added a trim pot to tweak the the V+ to the circuit.
The reason I did that was because in my observations the wah always sounds great just prior to the battery dying so I lessened it a bit with a trim pot.
Bc109 transistors, NOS Stack of Dimes inductor and some other circuit tweaks in a fixed format.
Anybody else got any wah mod pics?
Sorry but I just can't get enough of this stuff.

Regards,
George
