I've just recently gotten into doing a lot of recording, and everything sounds great, except for my guitars. They come out REALLY muffled. I run whichever guitar I'm using (Ibanez ART-300, Fender American Standard Strat) through a Boss ME-20 (Just an effects pedal) into a Peavey PV8 processor, and then into a Tascam US-100, because the Tascam overloads too easily with out it, and that then goes into my computer via USB. I have tried turning everything down and running directly into the US-100, but it still gave me that annoying muffled sound. Any Ideas as to whats going on?
