for my whole life i have run a pretty minimalist setup. usually just a tube screamer and a chandler echo. when needed (between songs) i'll patch in a vox wah or univox superfuzz, fuzz probe, whatever. i've resisted putting too many pedals on the floor because my tone (which comes from my fingers and output tube/tranny saturation just goes to sh!t. so i'm finally considering a loooper. are they truly transparent when in the bypass mode? do they need a buffer of any sort??? is there a superior solution to the loooper that i haven't heard of?
