Dunlop - 105Q Bass Wah

Hi, I search a bass wah schematics.
I know about 68nF cap change, but the final effect is not good as I hear 105q model of crybabe
Here is a short sample of 105Q

Thanks

try also using an higher value for the 1k5 resistor, i think this help a lot to brighten a bit the sound with such big sweep caps

The 105Q is a completely different wah; no inductor!
I once had a small peak inside one; lots of big IC's. Shame was that I had no time to trace it!

theres two versions..the newer one is all smt. So I think we might want to try to get an older one. I dont know when the change over was though.

The wah pot is a dunlop hotpot, 20k
the capacitor next to it is a 1uF tant.
Rp1 was a 470kA pot, but it got busted from travelling, and has now been replaced by the 2 through hole resistors you see there.
(as an aside, if anyone knows where to source a 470kA pot that looks exactly like the peak pot below it, let me know)
The peak pot (Rp2) is 100kA
and the trimmers
TP3: 20k
TP1(just below TP3): 5k
TP4:500K
The bottom 2 IC's are 4049
The top 2 IC's are MC33174 quad op-amps
let me know if you need any more pics

Thanks mr slunk very much. That was very kind of you.
Let you know if needed more clear shots or just to check values.
I hope other will "jump in" helping trace this fellow's schematic.
Cheers
edit: and we need volunteer to measure that smd shitty caps...

No go. They want to know whats wrong with it so they can help guide me in repairing it.
