So I dont want to have to go with active circuitry in my 79' Lawsuit P-Bass, because when I don't play with this 60's/70's Rock N' Roll keyboard lead band it sounds fine. I want to sound original by using the P-Bass on certain tunes that require it like Sister Golden Hair by Amerika and Midnight Confessions by the Grassroots. The keys are a lead instrument {with upper keys playing horn parts} and his left hand is so heavy he drowns the passive bass out and I dont want to fry my GK 700-RB or blow my SWR Goliath III 4x10 cab. Any suggestions? His reasoning for playing heavy left hand is because I add alot of fills above or around the octave on the neck and the bass drops out..but that is a cop out. I can blow him off his bench with my SX but it's hard to make the newer electronics sound old school and passive.
