The amp I'm talking about is a Peavey ValveKing 112, its a year old this month if that helps.

Now today I go and turn the thing on and I'm getting a muddy sound from it, sounds like it was just pulled out of the sea.

First I switch guitars, still the same muddy sound

Then I disconnected the Boss distortion pedal and use the on board distortion..still the same.

Checked the speaker to see if one of my kids didn't stick thier finger through it and that fine.

I still have the stock tubes and speaker on it

preamp tubes...change em to jj ttesla ecc83s....see if fyou like....if you still need a change, swap the poweramp tubes to some jj 6l6gcs or something. if it still sunds like crap (which it will) swap the speaker out.

ultimatelly you can get the amp modded from voodoo labs or something..all for around 300 and it ll actually sound good for a valveking one day.

most likely a bad tube.

go buy a new preamp tube that works and check each of the preamp positions by switching each one out individually and replacing with the known healthy tube. See if you can't find a culprit there. If you don't, you may need to replace power tubes which is a bit more of a hassle and a tad more expensive as you'd need to replace an entire set.
