Beginner project mods to reduce bass?

[BobP]

I love my pedal but it is very muddy to my ears. Are there some component changes that would brighten it up?

Hmmm something's wrong. It should not affect the bass response. In fact, it should brighten up the pedal a bit.

Is it a self made pedal? Are highs escaping to ground between guitar and Amp?

A good way to improve high end inside guitars themselves is to place a higher resistance Pot as volume control. for instance, 500k instead of 250, or even 1M. I imagine it might work like that for pedals too, if you have a spare pot of higher value you might try it.

Well I was looking at a fuzz pot article, and if you raise the decoupling caps, you can get more bass too, according to the article. however, it may not be just as simple as all that.

Note the caps. The reverse would be true. If you want less bass, lower caps.

The fuzz article also mentioned that apparently, for an output pot after the decoupling cap, A lower tone pot also lowers bass. Im not sure why, it sounds pretty opposite to a guitar inserted pot. Perhaps try both on a breadboard and see how the response is.
