Man Shaggy did an amazing job with this Mod! If you need anything done I would definitely go to Shaggy's Stompbox Mods on ye ol Facebook device. (I have even made it easy on you ALL you have to do is click on his name! :) )
It looks like my MXR Blue Box has wings!!! I can go one octave or two, I have a permanent volume boost, and now it even gets a little more harsh with the C11 switch.
