Ernie Ball Wah 6185 Mods

I have been on a kick recently to make my Ernie Ball Wah work better with bass, including downtunings. Here is what I have compiled so far.

I made quite a few changes. The rotary, pots, and toggle are mounted on the left wall of the enclosure. You will have to remove the back plate that protects the circuit board if you mount anything on the back. You can also change the inductor for one made by Eleca, Wilson, or Sabbadius

Shoutout to Stickman393 for his help with my initial questions and for finding different inductors to use with this pedal. You can make a stripboard version and stick it in your favorite shell. You can use an A250K like EB did, but that requires the 330K resistor in parallel. You can use a regular 150K Hot Potz without that resistor.
