Hey all. I'm posting this because I couldn't find any current info related to this and I think it will be helpful to someone with a similar project. I recently replaced the active preamp and pickups in my early 90's LB76 with a set of Bartolini 69j-l1 and ln1s and a passive V/V/T/T harness from Bestbassgear. I cannot express how good it sounds. I dont have issues with low output as other threads have suggested and the split coil 9js are dead quiet. I am running the neck pickup in the bridge and vise versa and the harness came with .047uf caps. Some threads suggest the the dual tone controls fight each other but I haven't experienced that yet. Have a gig with it this friday.
