i just bought a new G&L l-2500 (U.S.A Model) from a retail store online and it came with the certificate of authenticity and warranty registration. I didn't notice that i had to register for the warranty and i never filled it out. it has been about 2 weeks since i got the bass from fedex and it says on the slip that i was supposed to return the registration within 10 days of purchase. can i still send it in? also it came with a really bad dead spot on the 7th fret does this warranty cover this kind of problem or am i just screwed?
