Random Distortion Pedal

It really ain't practical to have effects runnin directly off of your guitar. It makes the guitar too heavy cuz the pieces required are too big. Also, it could mess with the plain tone of your guitar, meanin your guitar will sound bad with normal distortion or with clean.
or building a fuzz pedal. fuzz pedals are one of the simplest and effective circuits to build. A fuzz face only has a handful of components. And the rest of it would be routing out your guitar to get it and a 9volt battery to fit, and some toggle for turning it off and on, and wiring up pots to control it
