ok heres the deal.. I have a early 90's spector that was made in korea. Its a neck-through. I really couldnt find much info on this bass, but i'm learning more all the time. The pickups are covered and say spector on them in gold. I was originally told these were active spector pickups but i don;t think they are. I know it has an active preamp, but i'm thinkin about replacing the pickups with sum brand new active EMG's. IF i do that i have a few questions: 1. will it drastically improve my sound 2. How much and where can i get a set 3. which set do u reccomend (Its a P-J setup) 4. will these active pickups add another battery? 5. Do u reccomend adding a different preamp to these pickups. All in all i love the bass but i was told that this bass is identical to the USA NS-2's except for the pickups, so i want to get damn close to that USA sound. Thanks in advance guys.
