i repaired one a few months back. it is a pretty straightforward set of mods.

there is a second inductor ( red fasel ) that is switched,  off, series or parallel with the main inductor ( yellow fasel). this alone  gives the wah a lot of different Qs without a bunch of sweep caps like other mods have.

the components on the late model gcb95 seem to  be pretty much stock, possibly a few resistor changes ( look up vocal mods online for the usual changes). the transistors looked stock. dunlop buffer still in place. stock 100k hotpotz2, a very good choice for durability.

common gain/bass/volume mod, a 5k pot. i did not note where this hooked into the circuit.

overall, i think this was a well thought out set of changes, they didn't have to mess with the  board much at all. the mod wires tie into the traces on the back.

I am new to WAH modding as well as wah's in general.  I figured it is about time i add one to my rig.  I have modded a bunch of pedals so I need to bone up on Wah modding in general.  I was interested to see if there were instructions similar to his ds-1 mods....get an idea on what he is doing... I hate opening something up with no direction.

thanks

cool to know where you are coming from. welcome to our forum!

the most important component in wah modding is the sweep cap. normally the .01 or .015 after the inductor, heading to Q2. look it up.
