Re: know anything about BC Rich?
Tone is subjective, but IMO, yes, depending on the Gibson pickups you have. The Gibson 490/498 set did not work in my LP so well but they found a permanent home in my NJ Mockingbird. New pickups, along with quality audio taper pots, should be a good improvement.
The hardest part of selecting new pickups for the NJs (mine's an NJ Classic) is the maple neck-through construction and ebony fretboard. The tone is very bright and the attack is snappy and strong so you'll want to search for pickups with a softer top end. I also found high output pickups to be too harsh in the 'bird. The stock BSDM pickups are too bright, thin, and high output for those guitars, IMO.
