on going problem

I bought a Marshall JCM 2000 DSL (100 watt) a couple of years ago. A friend was selling it really cheap (probably so he could get high.) I love the amp, but.... I have a major problem with the footswitch. It will switch from channel 1 (clean) to channel 2 (distortion.) The amp also has the capabilities to switch between (for example) channel 1 A/ and Channel 1 B, and so on for Channel 2. Except this has never worked, I opened up the footswitch, everything looks good. Is there a chance that the problem is with the wiring in the amp itself? I don't feel brave enough to perform open heart surgery with a blindfold on. Let me know what you guys think.

And yes I know, I could take it to a tech and have him look at it... but I've gotten along with it like this for a long time, I was just wondering if there was quick fix that I could do myself, or if anyone else has experienced this sort of problem.

Thanks

Unless it's a special switch, I though the DSL would only switch between the 2 channels, and not the variations of the 2.

I'm almost positive it is supposed to switch between the two, I'll have to check the Marshall website to find out for sure.

Hey Rob....I had the same problem with my footswitch on my JCM900 a couple of years ago. Well, not exactly the same problem, here is what mine did. My footswitch has a channel and a reverb switch on it...It got to where I'd push the channel button, and nothing would happen. Then I would push the reverb button and it would change the channels. I never could get any reverb with the footswitch plugged into the amp. Anyway, I took it apart, and like you, couldnt see anything wrong, so I took it to a tech and found out the cable going from the footswitch to the amp had a broken wire in it. They replaced the cable, about $35 if I remember right, and it's worked fine ever since.

Thanks Joe, I may look into it, I might be able to get a new switch on ebay, or buy the cord and fix it my self. See you at practice.
