How to change Resistor to Trimpots in Vox V847 wah

[Clark Clint]

Hello I guys, I am new here and was wondering if anyone could help me out with some Vox V847 Wah mods. I'm not too seasoned yet in pedal mods, but I am learning. My question is, could someone explain the procedure on how to swap resistors with trimpots, I am wanting to add trimpots to the volume, and the bass and gain. Thanks for any info.

If you connect trimpot center leg to one of the outer leg, then the trimpot is a varible resistor with two leads just like resistor.Then solder the res out, and trimpot in. If you want to know where the resistors are in the wah, i cant help.

Really? I could but i dont know how to send pictures here.
But trimpot has 3 legs, so solder the middle leg( number 2) to leg number 1 or 3. Then you have two legs (or leads) just like resistor have. Then swap the resistor with that trimpot you made. Dont you have a diagram of the mods you want to make? You should know the values of the needed trimpots and so on before you can do anything...
