i dropped my amp a few months back and damaged something because when i play, there's a significant rattle/buzz noise combined with the note i play. i can't use this for any gigs unless it is fixed. i brought it to a store to get fixed and just got it back a month later only to find that it's still there ($60). i'm going to bring it back asap. what do you think the problem is? the store said it's possibly a cracked speaker but whatever they repaired didn't work. [wouldn't they test it first to see if it's fixed] it doesn't buzz/rattle nearly as much unless I play from the lowest E to around the A do you think I should bring it back to get it fixed [avoiding additional repair fees too because it wasn't fixed the first time] or maybe ditch it and get a new amp? I'm in high school, so I don't really wanna spend the cash on a whole new amp, and I like the one I have. But if I absolutely have to, then I guess I can find a way to make some money.
