To the Original Poster,
Instead of hacking up a pedal and killing it's resale value/warranty, you can definitely do something outside the pedal to better suit your needs. I noticed you probably wouldn't want to change your amp settings in order to get a sound out of the pedal that's more suitable for your specific needs. What if you made a true-bypass loop and hardwired a booster at the input or output of the pedal? This way you can get the desired extra gain or mids/presence. It would be a simple fix, which would eliminate the need for taking the pedal apart, "de-gooping," tracing the circuit, then trying to figure out how to mod the pedal.
