Another possibility is that your guitar might not be sheilded properly, especially if it's a single coil.
This problem is much worse when you have a TV, computeror flourescent lights.

Here's an awesome site

There's one of those in this household, too, but I haven't gotten around to putting a "high-cut" filter on it yet. (Info found in a review of that model on another site.) Your Marshall might need something like that added, although a filter can also change your tone somewhat.
Besides checking the house wiring, I'd suggest running the tests found here: http://www.guitarnuts.com/technical/electrical/trouble/index.php. That'll help root out noise sources in other parts of your setup.]]> Live Sound Doug_C https://guitarnoise.forum/live-sound/noisey-amp/#post-184712 https://guitarnoise.forum/live-sound/noisey-amp/#post-184707 Wed, 21 Jun 2006 19:33:38 +0000 This


Personally I use an AC outlet curcuit tester it looks like this


You can find them at hardware stores for around $10. If your not grounded I'm not sure how to fix the problem short of rewiring your house :oops:]]> Live Sound art&lutherie https://guitarnoise.forum/live-sound/noisey-amp/#post-184707 https://guitarnoise.forum/live-sound/noisey-amp/#post-18600 Wed, 21 Jun 2006 13:30:49 +0000

I've had it a few weeks now and I can't seem to get it to be 'quiet'. I don't mean that I can't get it to play quietly, because it will, what I mean is that I get an almost constant hissing sound with and without a guitar plugged into it.

If I plug a guitar in and turn on the Overdrive channel I get a slightly different problem - I get a sort of buzzing combined with the hissing, this time the buzzing gets less noticeable if I touch the bridge/strings on the guitar but unplugging the guitar doesn't have any effect.

I'm guessing that I've got a grounding problem somewhere, but is it a problem with the amp or a problem with the wiring in the house? Is this something I can fix myself or am I doomed to never be able to get a nice clean sound?

I love the amp by the way, it sounds great when it's cranked - I'd just like it to sound nice and quiet even when I'm not making a racket on purpose :)

Cheers guys.]]> Live Sound Catsworth https://guitarnoise.forum/live-sound/noisey-amp/#post-18600
