WOW !!! Seen my tech today and let him have the amp, he changed the 330mf to 1mf add a 250pf bypass cap to r8 on the board. Holy crap did that hit the spot on the leads. Slash tone leads in spades with the ppimv it doesn't change one ounce from wide open to mouse fart. I'm still working on the bass but in reality it's perfect on zero. Just amazing sound. Those who don't think the ppimv with pedals get good tone I strongly disagree because this is fat lean and mean stuff.
