Ok all you tech people, I have a 4 string Fender Marcus Miller. I want to put a three band Darkglass pre in it with volume and blend. Is there a pot I can get for passive pickups that’s stacked with a normal volume on the bottom and a center detention on top for the pickup blend? Is this even possible? I don’t want to put more holes in the bass than the 4 stock ones. Oh, and I still want to have the active/passive switch work. I’m replacing the pickups with some type of hum cancelling jazz bass pickups. Haven’t decided yet. Probably Duncan Apollo set.
I don't know about the indents, but stacked knobs are out there for multiple purpose. You should consider wiring it like my Sandberg Grand Dark. It seems logical to me and maybe the easiest scheme. It also has the Darkglass preamp. It's setup as follows, going from top down; First knob is volume with push pull passive/active. Second knob is blend. Third is mid. Last knob is stacked treble and bass.
This dude kind of explains it at 2:50 seconds.
