Okay, I've removed the frets and unscrewed the main speaker to check the connection behind. Nothing seems amiss there.
Could it be the amplifier? The top speaker is working.
I don't pretend to know what I'm doing, I'm really just after some advice as to the feasability of repairing this. Is a new speaker an expensive purchase?
Is a failed speaker or amplifier a common problem with the Century?
Cheers
