I see stuff about the fender tone stack mentioned every once in a while... particularly that it is "cut only." Also have heard that flat on a fender amp is treble at 10, mid at 5, and bass at 10 (or something like that). Is this true? Can someone help me out a bit with what this means. should I start with my tone nobs up at 10? Also, my amp - Fender bassman 100 - only has treble and bass on the bass channel that I use.
