I got a loan of a Warwick x-treme 10.1 bass amp for a gig. I was checking levels with the drummer when the amp blew a fuse. We got the fuse replaced, the amp powered on but then there was no sound! I took everything home after the gig, the cab isnt the problem, I tried it with a different head. Its not the bass or any leads or cables.
I know the head is recieving a signal because when I crank the gain and slap the pickups, the red clipping light reacts. Has anybody any idea what's going on? Is it fried or is there something I'm missing?
If anyone has some advice on this it would be greatly appreciated. I'm in that awkward situation now where I borrowed somebodys gear and it's returning broken!

Help!!
