One of my Marshall’s has a strange issue in that it sounded amazing at the store when I got it and sounds horrible at home. I took it to a local shop to have a tech look at it, thinking possible microphonic tube but I could not replicate the sound-it sounded amazing again. Took it home and again, crappy! A friend took it to his house and said it sounded great.

It sounds great on the Low E, A and D string but on the G and B and high E, it almost sounds like I’m fretting the notes right on the fret, rather than between the frets. That’s the weird over tone I’m getting.

I initially tried a different outlet/room and when that didn’t work, I tried a power conditioner and that didn’t help either. Any suggestions? I’m assuming it’s my house because it doesn’t do this anywhere else. I’ve tried different guitars (Les Pauls, Strats) and they all sound the same through this amp. Although, the single coils sound better that the humbuckers. On my deluxe strat it sounds okay but when I engage the S1 switch it gets worse.

Thanks in advance...

p.s. all of my other amps sound good at home.

Sounds like it may not be a keeper, if it's *only* your house where the issue happens.

Haha, no doubt!

 

[Budda]

Sadly that's all I've got haha. The only other suggestion I can make is to try it at a friend's place and if that seals the deal, pass it along.

I was thinking of just moving to a different house.

What is the size and type of room? Is it in every room in your house? Change your room acoustics and see.

Check your power with a meter and see if it is low, high or fluctuating.

I’ve tried the living room and Family room but good idea. I’ll check the outlets and then try upstairs.

Did you check the voltage at the wall socket?

Along with voltage, check that the outlets you are using were wired correctly. Any crappy tire should have a receptacle Polarity tester for cheap.

I've seen so many cases where a wanna-be electrician made full use of his imagination in order to get the job done.

Not yet, I can’t find my multi meter so I have to go grab a new one. Amp sounded crappy upstairs too. *#*(

Thanks for the link, I’ll grab one of those as well. Our house was built in the 90’s but a lot DIY work done. I’ve been trying to get electricians into the house as I have a few outlets and electric baseboard heaters that aren’t functioning. Unfortunately, I kept procrastinating....now it’s affecting my tone so time to make the call. Lol

Without Tone, a house is not a home.

Who needs heat and functioning outlets if you don't have tone! Priorities, people!

100% agree! It also Sounds like a good theme or line for a country tune. LMAO

Exactly!

 

[nonreverb]

If the voltage is exceptionally low, definitely a wiring check would be a necessity.

Is this a combo? Or are you taking your cab along to the other places?

It’s a combo amp.

 

[gtrguy]

Maybe record a little clip so we can hear what you're hearing?

 

[Player99]

Run an extension cord from your neighbour's house to check your power.

 

[seadonkey]

I tested the outlets and they all came back correct (green light) so I moved onto checking the voltage. First outlet I checked was 104.6 so I figured I had found the issue. I then went and checked a bunch of the outlets I actually use for my amps and they all came in at 117 which I assume is close enough to 120 to rule out as the problem.

 

[jb welder]

If you have noise on the AC line, the voltage will measure correct, and the tester will give a green light. Anything different in your house or in the neighbourhood that could be putting noise on the AC line?
And monitor that 117V you checked while you are playing. If it is dropping to 104V or something while you are playing, you may have a wiring fault in your house.
Also, don't be afraid to give it a thump with the palm of your hand or a rubber mallet, in case there is some intermittent connection. And if it has an FX loop, put a patch cord between the send & return jacks (or sometimes called pre-out & power amp in).
