Amp is making funny noises?

les-legend	Date: December 6, 2005 @ 6:34 AM heey guys.. i got a Marshall AVT 100, and i really love that amp, awesome sounds. Im playing with a Ephiphone Les Paul Standard. My amp makes some noise though, i can hear the noise when im not playing, but when im playing i cant hear it. Does anyone have an idea why its like that? What can i do about you?

psypig	Date: December 6, 2005 @ 8:12 AM what kind of noise?
hate9wicket	Date: December 6, 2005 @ 11:47 AM check your cables first, also you may just be standing too close to it.
psypig	Date: December 6, 2005 @ 12:18 PM also what kind of guitar are you using?
EtherEclectic	Date: December 6, 2005 @ 1:40 PM hot pickups maybe? might require a few feet away from the amp. i have to do that with my artcore, i need to be at least 3 feet away from the amp otherwise at high levels it starts making all sorts of racket!

zedsalt	Date: December 7, 2005 @ 11:46 AM Fluorescent lights can cause a hum. Make sure your cables are clear (anyone who has seen this pic http://files.dmusic.com/music/z/e/zed/studio2.jpg probably thinks I'm being hypocritical, but trust me, I untangle things before recording). Unplug anything with a three-prong plug one at a time; if you find an offender, make sure that either it has an adaptor and nothing else does, or vice-versa. Check to see if the sound changes when you touch the strings, bridge, tailpiece, etc.
Alecs	Date: December 7, 2005 @ 4:39 PM What are the funny pitched noises? A high pitched squeal? A hum?
les-legend	Date: December 8, 2005 @ 10:21 PM It is a sort of a "humming" noise, and i cant get rid of it..It is not very loud, but its still anoying me. The noise is a low pitch noise, it hard to explain.. Thanks for all your replies though (even though the noise is still there).. The guitar im using is a Epiphone Standard Les Paul
Alecs	Date: December 8, 2005 @ 10:29 PM I'm thinking your ground wire isn't properly soldered. Take a look at that.
Alecs	Date: December 8, 2005 @ 10:41 PM I should probably clarify more. The ground wire on your guitar is a wire that goes from the controls and attaches to a piece of unused metal (like the springs on a tremelo). It is used to channel off the excess energy, that energy is what causes hum, usually. If your ground wire has somehow come detached, you're definitely getting hum from it. It could be something else, but this is my guess
Veracohr	Date: December 9, 2005 @ 12:34 AM Sounds like 60 cycle hum perhaps. 60 cycle hum is noise generated by the AC power your gear is connected to (AC power alternates at 60 Hz, or 60 cycles per second). The hum isn't necessarily always 60Hz; sometimes it's multiples of 60Hz: 120Hz, 180Hz, etc. Unfortunately, it's not always the easiest thing to get rid of. I spent a few minutes Googling for an answer for you, but couldn't come up with anything decent. I know I've read about it in the past, but I don't have an answer ready in my brain. The only thing I found sounds like overkill for a guitar rig: plugging your equipment into a power conditioner. And not just a cheap one But if it's not 60 cycle hum, I don't know what it is based on your description.
GeneHilbert	Date: December 9, 2005 @ 2:35 AM This is a Transistor amp, with built in effects..... Is this correct......? 1. When you hear the hum what is your amp volume set at? 2. Is this clean or do you have an overdrive punch in....? 3. What pedals are in the signal chain...... if any......?
TameasDust	Date: December 9, 2005 @ 4:09 AM record the funny noise and then take the hamster out of the back
imemine	Date: December 9, 2005 @ 9:56 AM Sounds like you have a clown loop in the defunkulator circuit of your post amp to me! I.e the “funny” noise….or if it’s just humming, perhaps it just doesn’t know the words.
victorsskull	Date: December 9, 2005 @ 10:00 AM sounds like your lithium crystals are running low go to planet voltron and buy some new ones
TameasDust	Date: December 9, 2005 @ 10:20 AM probably just cranked it too high and placed it next to the tv ... or his sister washed it in the bathtub and forgot to tell him
