Need some help- special ordered this Bass from my local music store 'cos I wanted something more "metal" for my band, and it is EXTREMELY HOT!!! Wow does it blow the doors off!!! Lately it has been losing sound, so did some "investigating" and found out that not only are these active pick-ups, but 18 volt as well!!! (I specifically ordered it with passive pick-ups). So this explains WHY it is so Ass-Kicking Loud but can ANYONE explain to me what the benefits are of this being a 18 volt system? Peavey has NOTHING on thier web-site to explain anything about this system...
