any of you ever put a voltage pot instead of cap on your pedals? i want to do this to my digitech grunge because i only like the sound when the battery is low... i've seen a site giving instructions on how to put a "dying battery simulator" into an external box, but not onboard an effects pedal. oh and to avoid any confusion, the digitech grunge is all analog, so this mod would have a positive effect (dying digital pedals just suck)

Yeah I been wanting to build one of these but haven't had time. I think RG keen created this but I'm not sure.

Rg Keen is the God father of boutique pedals. he designs the boards for the visual sound pedals

yea thats the site i saw the mod on... im pretty sure he did it externally. i saw his 4 fuzz pedal he made and it looks so fricken awesome.

he's da man!

He worked for IBM designing power supplies for years while posting free pedal building articles. If I get stumped that's where I go!

sounds like a cool idea
