I'm in some trouble...

..and it has to do with my amp.


Last Thursday at a gig my amp cut out. The signal just stopped halfway into the set. So I haven't touched my amp since Thursday until a few minutes ago annnnd its still not making noise. It turns on and its not my guitar because I've plugged it into 2 different amps since Thursday and it works fine. I think the problem is where you plug in the cable to go from the head to the cab because I noticed it was warm when I touched it Thursday night. Could a solder have come undone inside the head? I need help on this quick.

Thanks guys.

First check all of the fuses. Some amps have fuses on the circuit board as well as the main power fuse (where the AC cord attaches).

Pull the amp out of the case and check the speaker jack and its connections. Have you tried plugging the amp into another cab? Maybe it's a connection in your cab.

Take the amp to a tech! Don't go poking around inside there if you don't know what you are doing. It could be a tube, but the best thing is to take it to a tech!

+1
the caps in there have dangerous voltages
and could kill you dead

that would seriously affect your guitar playing


please say you aren’t using an instrument cable to connect the head to the cab

If it's the Randall RG-100 in his sig, I think that's a solid state amp.

Re: I'm in some trouble...

I got it fixed. The send and return in the effects loop were dirty so all I had to do was spray them a bit and now everything is fine.

Re: I'm in some trouble...

Edit (9/17/12): The amp is goofing up again. I'm going to have a tech look at it this week. If this keeps on happening I'm just gonna save up for a Blackstar HT-50.

Anyone have any ideas for stuff I could do to maybe fix this without spending too much cash? Could it maybe be that the cab I'm running doesn't match up at far as the Ohms are concerned? The Amp is 8 ohms. I'm not too keen on the whole ohms deal so some help with that would be really nice.

dont buy a new amp. just take it to a good tech and get it diagnosed and serviced.

If the last time it was the effect loop send/return, it could just be any or all the input jacks... try spraying them all out with contact cleaner and just put a jack in/out several times. It could just be carbon build up.
