Hi gang, My Crate BT1000 bass solid state combo amp started acting up recently. I've noticed the last couple times I've turned it on it produced a hum that was never there before and then it would go away after a few minutes. The last time I used this amp this weekend it hummed when I turned it on but then the hum did not go away. In fact, after practicing with the rest of the band for about an hour or so my signal cut out completely! It has a built in tuner on top and it was still giving a read out when I played but no sound out of the driver. When I got home after practice I tore apart the cabinet and found nothing suspicious that would cause my sound to cut out. All of the connections to the driver and other parts of the amp were fine. The fuse had not blown. I put it back together and tried again. Same hum but then my bass would cut in for a bit and then go out. It is very strange. To me the driver seems fine. I'm guessing it has to be something in the electronics of the amp that would be causing this problem. Any help is appreciated. This has been a great bass amp thus far and I would love to fix it and keep using it. Thanks!
