So I bought this brand-new bass guitar from Guitar Center on...I believe it was 7/31, since the 30 day return policy expired on 8/31. It's a real beauty, six strings with lots of tone knobs. And up until now, it's worked just beautifully.

Last night when I was jamming with my friend, my amp started making a weird clicking noise (if you need to hear it, I can record it when I get home), and no notes would come out when I tried to play. I thought it was the cord I was using at first, so my friend gave me a fresh one. Still made the noise. So I thought maybe my FX pedal was fucking something up, so I plugged the guitar directly into the amp. Clicking noise was still there. So then I thought it was the amp...but when I plugged it into my friend's guitar amp (a state-of-the-art Marshall amp), it still made the noise, definitively proving that it was the guitar itself.

I'm sure it's some kind of connection problem involving the input jack, but what do you think? Also, if it IS some kind of connection problem, what is your prognosis on how much it will cost to get it fixed?
