Modifying wah pot

[YouAre]

I've got a BYOC wah PCB (basically a vox/crybaby with an output buffer) with a 200k icar pot from smallbear.

Its a great sounding wah, sometimes, its just a bit too warm/mellow for me. I'm pretty sure its the 200k pot. Would putting in 2x 100k resistors in parallel with the two main lugs successfully bring it down to 100k without totally screwing up the taper? Are there anyways that i can use resistors to adjust the range of the pot in the wah?

i dont think that may be the case...

whats the input resistor?
Q? bass/gain?

  I started two 100k's from wiper, one to each outside lug, through a switch.
  On a 200k wah pot I got from SB, this mainly increases the sweep per treadle movement amount [quick sweep].
  Warm/Mellow...I would say look at the pinion gear indexing, the actual value of the pot probably won't change the warm/mellow thing much.

First, the common belief (I have not tested this) is that a 200k pot makes the wah slightly brighter, so lowering it's value will likely not help your problem.

Second, putting a single 100k resistor across the outer lugs of the pot should make it a 100k pot.

  2 x 200k parallel [as in the pot and trim resistor or resistors] = 100k.
  100k with 200k paralleled would be...some math or a circuit test for me to find the exact value, I guess around just <82k, which is probably close enough for wah purposes, YMMV, for quicker wakka/wakka sweeps...
  The sweep 'curve' of the pot and wah may experience some 'bunching', as smaller fixed parallel trim resistors [small in proportion to the pot value] are used.
