I've heard a lot of people talk about the "dying battery" sound of a fuzz (looking into my first one currently). However, having just acquired a Furman pedalboard - with extra space...hence the fuzz GAS lol - it seems like it should be fairly easy to replicate that (and what the PP2 does) using the power cables. To be it seems like you'd just need a small box (I'm thinking T1M mini size), a pot, two Boss type jacks, and you should be good to go, right? Ideally maybe a switch to reverse the output polarity to match various fuzzes. So my questions is... Is this right? Has anyone done this? Does anyone sell these already (haven't seen them)? Does it even matter? Thanks!
