Hey Nicky!
Good to hear from you on the Roscoe forum!
Let us know the results if you try the CB's passive. Personally, having played passive Fenders for years during my early years, and having played newer basses with the nice on-board pre-amps, I just don't see why players would want to go back to passive, other than a backup to pre or battery failure.
I run my amp flat and love the ability to tweak the EQ at my bass for changes in my tone, and that's primarily limited to panning between p/u's and a slight mid boost. Hey, but different strokes for different folks.
