A while back I mentioned in a thread that my JCM 900 would sound great and then the volume would drop off dramatically almost to a whisper, and then come back to full volume. The tubes were ok. I just had the amp re-tubed and re-biased. Someone suggested I spray electronics cleaner into the main input jack, then the effects loop and work a guitar cable in and out of the jacks a few times. It worked! I haven't had an issue since.
Last night at a gig I was using my JCM 2000 and the same thing happened. Crushing tone from the start and then the sound dropped off, came back full, dropped off...I turned the standby off for a minute. I was worried I had a bad tube as I haven't had that amp worked on in a while. Tubes were ok. This happened in the middle of a 22 song set, went on for about 4 songs and then stopped and I made it the rest of the way without a problem. Amp sounded as crushing as ever. I got home this a.m., sprayed the electronics cleaner in the input and effects jacks and I played at a real low volume for over an hour with no problem, no volume drop.
I'm surprised it would happen to this amp, I baby this thing. I only play it at gigs so at most it's used 4 times a month. I have a cover on it all the time and when I do play it the volume is never past four on either channel. What exactly is happening in those jacks that causes this?
I'm bringing it to my amp guy for a checkup just in case. This 2000 is my tone, I can't mess around with this thing.
