Due to a bad gigbag i dropped my series 3000 yesterday. I thought it would be no problem, I have dropped it one time before and that time it wasnt in the case :)
So when I came home i looked at it, no obvious damage taken, eventhough the e string was badly tuned.

So I took it to rehearsals one hour later, only to find out i couldnt get any real volume out of it. Today when I woke up I tested pluggin it in my amp and no problem - It sounded like it always did. I also opened the bass and I couldnt see anything strange - although Ive never opened it before :)

Ive never heard of a bass losing its voice B)
What do you think I should do?

I would check cables/pedals/outboard/amplifier before the bass.... cables are normally the weakest link in any system.
