I have an '89 MIJ P-Bass which I love to play but sounds weak compared to my vintage G&L's. (L-1000, L-2000E and SB-2) So, I'm considering changing the pickup and the Darkstar option is intriguing. The expense gives me pause because it looks like I'd have to replace the tort pickguard I just put on it in addition to the routing. If anyone has any advice based on their experience, I'd appreciate it. I would also consider other types of pickup replacements. I mostly play Classic Rock and Blues.
