Hey all, I've been seriously looking at a Spector bolt on in my local music store. It's a Czech made and is basically the parent bass of the re-bop. It was released only in Europe and one made it here to Canada. Now the new rebops come with an Aguilar Preamp (OBP-1 I beleave) but I was told these ones came with an EMG active preamp. So I was wondering if any of you guys could give your opinions or comparisons between the two Preamps. Thanks alot guys, just want as much info as possable before I drop a grand on this beast!
