So, i have been playing bass for about 3-4 years, yes i know not long at all but i play in an actively gigging band. So when i got my first stack is was this dusty old thing that my neighbor kept in his basement with a custom build cab and a Fender BXR 200 head. My problem is that the speakers recently just went crazy on me and both of the speakers suddenly get extremely loud buzzing when i play on my A string this started 2 days ago with all my normal settings on my head. I know its not the head because i have checked it with a friends cab. Also, one speaker is completely destroyed. SO i was wondering what kind of speakers should i replace them with or if i should just buy a whole new Cab and is the head i am using is right. if you need any more pictures please ask, i am desperately in need of help since my band has a lot of shows coming up.
