A while ago after reading threads on clean tone, headroom, pedals and pedal stacking, I decided to try using the controls on my Fender Novena Stratocaster as well as my pedals while keeping the gain and master levels on my Mesa Fillmore 25 around noon. Until now I've had the volume and tone controls on the guitar set to ten. To my surprise I'm finding more tones available giving me more control over my sound. I've read about the relationship between P90's and the guitars control pots but its another thing to actually experience it. I'm probably preaching to the choir but I'm just having fun playing the guitar and these forums help.
