I have a Spector NS2A with the "Spector" pickups. This is a late 80's Spector and if I remember correctly, the bassists who were using these basses during that era just pulled the Spector pickups out and dropped in EMG's. Anyone remember if that is right? Or did they change out the pre-amp too? I think its a Hazlab preamp. Is changing out pickups a pretty easy job? I'm getting back into playing after 15 years, so I'm kind of relearning all this. Any help is appreciated!
