I have a 5 month old Schecter omen bass, and it suddenly stopped working. I took it guitar center where I bought it and the tech said the preamp was blown. I don't know what I could have done to do that...I just plug it into the $100 bass amp and play. I think it must have been faulty. But my question is whether I could have done something to blow it out...how can you blow one out? Any ideas?
