hi, y'all. I have a Fender Deluxe 112 Plus amp - got it cheap, cause it had a crappy speaker in it, wrong ohm rating and probably a bad coil.

I replaced the speaker with a correct (Fender) 12", 4 ohm, 100 watt speaker, but it seems really noisy at rest unless I dial down treble & mid to zero. This is a solid state amp, and I'm not good at volt/ohm meters, schematics & circuitry, so I'll take it to a tech (maybe) if it needs it.

Anyone know why it's so damn noisy? I also have a Champ 25 SE, which is a really nice amp (with tubes) and it's almost silent at rest. Of course it's a little noisy at rest w Drive circuit open, but that's ok.

Also, the Deluxe 112 Plus speaker seems kinda muddy when I crank it. Is this typical? I'm talking single pole and humbucker pickups - runs muddy w both at vol 5+. The Champ 25 sounds a lot better to me.

If you have any ideas why the Deluxe 112 Plus is noisy & muddy, PLEASE let me know. Wanna buy it? I'll give ya a good price...

:idea: I have owned a 112 Plus it had a semilar problem I cleaned the Volume, mid , and Reverb Pots and 80% of the hum and noise went away. I now have a Stage 112 SE and it as had the same problem, and this fix worked on it to, this helped clear up the sound also. Hope this helps you out.

kgambler44 - thanks so much for the reply. I'll have to try that. Can you recommend a pot cleaner? I know enuf not to use WD40 - but I don't know what kinda electronics /potentiomerter cleaner spray to use. Years ago I used some teflon spray on an old Gorilla amp I had, and it worked well, totally cleaned the noise out of the pots, but I think there must be a better cleaner out there. Can I find something at Stew-Mac? Please let me know, and again, thanks!
