Dying Battery Voltage Mod


I created this mod for the Big Muff but it will work with every pedal I now offer a mod for. It is a well know fact that in some circuits as the battery weakens it can have a very positive affect on the pedals tone. On the Big Muff the affect is just plain cool. The gain takes on this very fat blooming gain. Very nice!

And it a very simple mod to do. You will need to drill a hole for the pot but then it’s just a matter of connecting a couple of wires and that’s it. When time permits I will add a video of the mod.
