Mark IV RHY 2 and Lead problem, help!

[espmaster1]

So whenever I get into any of the 2 channels listed, (RHY 2 and Lead) it sounds like the amp isn't plugged into a guitar. But I've tested 3 guitars and it's happening with all of them so it isn't a problem with a guitar. But recently I tried fixing the prongs where the FU-3 switch goes because they were bent, but that couldn't be causing it, could it? The noise is liike an intense feedback and I don't get any when I'm in RHY 1.
I would normally think It's just feedback but it comes through when I'm playing. An intense buzzing noise, anyone have any ideas?

Try swapping your preamp tubes one at a time with a known good tube.

Thanks man, I'll give that a shot.

Another weird thing is also the fact that it is directional... when I'm facing the amp it's worse, like it usually is. But it is just significantly worse than it used to... I didn't touch the guitar or amp at all. So I don't know what it is.

Most high gain tube amps will hum louder when the pickups are facing the amp or too close. Cheap pickups and cables do not help either.

I'm using all gold tipped monster cables. So I don't think the cables are an issue.

By the way boogiebabies, I appreciate the time you're putting into my problem, I greatly appreciate it!

You can fix it by dicking around with the preamp tubes .

Even with "new" tubes , swapping them around can fix it ..given some time and positive mental attitude .
It can become ... obsessive .... ; anyway ,

Buy extras'
Send the baddies back

Worth it though . HeH .

I was being sarcastic . If you are going to be so non heinous , George Carlin will time travel and show up at your birthday party .

Most excellent .
