the blend pot on my warwick vette 5 (glorified jass bass?) is almost always right in the middle. ill roll it slightly to the neck pickup for slap or more of a "P" tone, or ill move my right hand back towards the bridge when soloing to cut through the mix more. as my playing style has matured, i fiddle around with my knobs less and use my hands more for tone and dynamic control. my EQ has gotten much flatter over the years too.
