Yes, I know there's a thread on this same page about fretless j pickups, but I think my question may differ. I have a passive Cort Action V. The pickups sound really thin. I like to favor the bridge pickup. I really want to drop in some humbuckers (to complement my active 6 string.) I'm wondering though, could this sound thin due to my EQ'ing? I don't change the EQ when plugging in the passive 5 vs. the active 6. So anyways, would it be a good idea to just totally overhaul my bass by bringing it to a guy to dremel out space for a humbucker (soapbar or MM?) and keep the J in the neck and have him make it Stacked Treble/Bass, Pickup Selector, and Master Volume, or would it be better to just drop in a stacked humbucker? Sorry if you can't read my rambling.
