Hello, I'm new to this forum and this is my first post.
The reason I'm posting is this;
I bought a Marshall Valvestate S80, 40 watts (model 8240), from a friend today. I got it pretty cheap because we knew that it wasn't in it's best condition.
Anyways, directly when I turn the amp on, I get a pretty loud buzz/hum or whatever you could call it. It's there even when all the knobs are turned off and I tried all the buttons but it won't go away.
Well, that's not really the big problem. This is really wierd and I don't know really how to explain it. The thing is, when I start to play, I get this really wierd sound, almost as an effect was still on, like flanger/chorus or maybe a reverb, even though all the effects are turned off. I get this on both channels, but I believe it's worst on the gain one. I can turn it up pretty loud and still play as usual but it sounds like crap, not like a speaker has been blown, but just that freaking wierd, bad sounding effect.
My friend telled me about how it first got there. I wasn't there when it happend so I'm not entirely sure but this is what he said happened;
He just got it, but I think it was from the 90's or something, turned it on and it played really good, then he put on some reverb. But he was rehearsing with his band so I guess he took the volume all the way up. Then he took his (dist?)pedal between the amp and the guitar but when he turned it on he heard some kind of sound/pop/boom, I don't know. And after that, it sounded really wierd, kind of like it does now, I guess. But then when he switched to the clean channel it was all good.
The next day when he turned it on though, it sounded just like it did when the accident had happened the day before!
I'm sorry for this wall of text, but does anyone of you have an idea what could have happend and if there's any way to make it work good again?
Thank you, hoping to get some kind of replys, hehe.
Peace
