I have a Peavey Classic 30 combo amp (tubed). There's a channel switch button on the amp that is meant to toggle between the clean and distortion channels. However when I attempt to toggle from clean to distorted, I get no distortion. The tone stays clean. I've had the amp for about 5 years now and it used to work with no problems. How can I get the amp to properly switch to the distortion channel? Is it something I can do myself, or will I need to take it to a music shop

Are your tubes turning on when the amp is turned on? I know if the tubes get too hot everything sounds distorted so if some of the tubes are damaged it may cause there to be no distortion. –  Dom Dec 30 '13 at 16:31
    
@Dom - Yes, all the tubes seem to be good judging by the looks. Some tubes are more illuminated than others, but it seems like that has always been the case. –  hgwhittle Dec 30 '13 at 16:35
    
Is there maybe a knob on the distortion channel (Gain or something) that isn't turned up enough? –  Shevliaskovic Dec 30 '13 at 21:44
    
@Shevliaskovic - Yes there is a Gain knob but I've tried twisting all combinations of controls to no avail. –  hgwhittle Dec 30 '13 at 22:06
    
This sounds most likely a problem either with the toggle switch or the footpedal connection. I can migrate to the electronics StackExchange for you. –  Dr Mayhem Jan 6 at 22:51

With a couple of my smaller Peaveys, the amp. switch works in conjunction with the footswitch. When the amp. switch is 'on', the footswitch will then toggle between clean/dirty. You may have inadvertently switched the footswitch, which you may or may not usually use.Check the instructions (downloads available) before doing anything drastic. Do not swear at it - amps are very sensitive ...

So are you saying the amp could "think" that there's a footswitch plugged in? –  hgwhittle Dec 30 '13 at 19:24
    
I'm saying that if the footswitch is in, it may need switching on. –  Tim Dec 31 '13 at 20:21
    
I don't own a footswitch. –  hgwhittle Jan 2 at 15:07
    
Well, it can't be that then ! Lots of Peavey amps have a socket in the back to connect a footswitch for channel change and reverb. –  Tim Jan 2 at 15:35
    
It does have a port to connect a footswitch, I just don't have one. That's what I meant from my earlier comment. It could be that the amp is acting as though a footswitch is plugged in, even though one isn't. Possible? Maybe? Not sure. –  hgwhittle Jan 2 at 15:57
