Elliott Posted September 30, 2008 Posted September 30, 2008 Hello again ! Okay, I get in my house, go straight to my guitar, and spend ALL night trying to get rid of feeback. I dont even play anything. Im sitting there for 4-5 hours JUST trying to get rid of this feedback. Ive played with all the dials on the guitar, spun all the dials on my amp, tinkered with all the dials and switches on my effects pedal... For nothing. Please, its driving me absolutely CRAZY !
phantomface55 Posted September 30, 2008 Posted September 30, 2008 Has your amp or guitar been in any contact with magnets?
Elliott Posted September 30, 2008 Author Posted September 30, 2008 Nope. Ive tried everything and is the most annoying thing ever.
leicester35 Posted September 30, 2008 Posted September 30, 2008 To trace the problem, I'd go back to basics. Forget about your effects pedal for the time being, and keep the signal chain clear until you've solved the problem. Try a different cable - preferably a good quality one with a decent length to it. Turn down the gain on your amp to a fairly low setting, set the bass / mids / treble to 12'o clock. Dial in a clean tone - keep the volume reasonable. Reverb setting doesn't matter - just set it to something average. Don't sit over your amp. Plug in, and play some distance away from your amp. Keep the p/ups of your guitar turned away from the face of the amp. Roll a little volume and tone off the guitar. It should be clear as a bell. After that, you can start experimenting with your amp settings, and try and find out where the feedback starts...kind of like finding the biting point on a clutch. To be honest, I'd be surprised if it turned out to be guitar. I find good Epi p/ups (like their Alnico Vs) to have a lovely tone, but they're not super hot. What amp are you using...is it some high-gain solid state metal job? Is it 1 or 2 channel? If so, does the feedback only affect the overdriven channel?
Elliott Posted September 30, 2008 Author Posted September 30, 2008 Nice one, I shall try all of that. And about my amp, Ive had it for about 4 years... Wait for it... Its a stagg practice amp. =/ Its small, and its rubbish. No channels, except (obviously) a drive button. But that doesnt really count as a channel.
Stevie Nazarenie Posted September 30, 2008 Posted September 30, 2008 get a nice amp modeler with a noise gate and just use the amp for amplification not distortion. try a pocket pod if money is an issue. some amp models cause noise but you'll find one you'll like. ohh. do you mean microphonic feedback?
Elliott Posted September 30, 2008 Author Posted September 30, 2008 ohh. do you mean microphonic feedback? I have no idea what I mean. Lmao. All I know is that it is so annoying, and high pitched, and it wont go away. What are the types of feedback, if that is what you are implying ?
Stevie Nazarenie Posted September 30, 2008 Posted September 30, 2008 when you use a high gain amp up loud you can "control" feedback and get hendrixy feedback you know touch the strings and you can stop it. microphonic feedback is at low volume and you touch the strings and it doesn't stop it. it's like if you point a microphone in front of an amp. high pitch squeel. i had this on my fake epi. the pickups were meant to be wax potted but there was no wax under the pickup covers. old pickups can go microphonic if the wax degrades but newer guitars should be fine unless you got it off ebay like me! wax potting can cure it but... http://www.guitarnuts.com/technical/electrical/index.php
Elliott Posted September 30, 2008 Author Posted September 30, 2008 I see. Yeah, when I put my hand across the strings, I still get feedback. (This is hard to explain) But when I put my hand on something metallic, like some screws or the actual pickups, the feedback stops. Strange.
Memphs1978 Posted September 30, 2008 Posted September 30, 2008 dude i think you have a sh!t cable or a crap ground... it sounds like your getting bad signal in you cable or your amps not grounded....
Stevie Nazarenie Posted September 30, 2008 Posted September 30, 2008 so it's a squeel not a humm? if your amp was valve i'd think one of the valves could be going but i think it's tranistors so it's the pickups. does anything change if you select different pickups. i'm just wondering if you can find out which one. loose coils of wire cause the problem which the link i posted can get you sorted. i bought the parafin wax and beeswax off ebay to solve my problem when i found mine was not a real epi. the pickups sounded good! but the squeel made them unuseable.
Stevie Nazarenie Posted September 30, 2008 Posted September 30, 2008 in case you missed it. http://www.guitarnuts.com/technical/electrical/index.php i had this problem on my 87 gibson sg too.
epilover9568 Posted September 30, 2008 Posted September 30, 2008 I see.Yeah' date=' when I put my hand across the strings, I still get feedback. (This is hard to explain) But when I put my hand on something metallic, like some screws or the actual pickups, the feedback stops. Strange.[/quote'] I am a professional guitar technician.... So, please take my advice knowing that.... Its 99% probable that your electronics are not grounded properly... Usually its the wire coming from the switch to the pots that is either not connected or connecting with a hot... Go get a long wire stripped at both ends, open up your back panel, touch the switch on one end to the pots on the other. Does the hum go away ? If yes, you need to connect the switch ground to the pots.... Do the same test for all pickups, pots, and input jack.
Ricochet Posted September 30, 2008 Posted September 30, 2008 Try another guitar with the amp. And stay away from fluorescent lighting and your PC-monitor.
Stevie Nazarenie Posted September 30, 2008 Posted September 30, 2008 any chance you could take a photo of the control cavity while you're at it? i' like to see the wood too. gibbo did ask for certain parts of my guitar to be photographed but they did not ask for the real tell tale areas which were the control cavity and the pickup cavity. i threw those photos in for good measure!
charlie brown Posted September 30, 2008 Posted September 30, 2008 Has this guitar JUST started doing this, or has it developed over a period of time, getting worse, as time goes on? If so...they (the pickups) may be going "mircophonic," and need to be rewound, or maybe just wax potted. DO check all the things the others have mentioned, but high pitched squeal, was something my LP Deluxe started doing, more and more, until it was (basically) useless, to even plug it in. I sent the pickups off, to be wax potted, got them back, and there's no sign of the feedback, at all, now. The pickups sound fantastic. Probably better than they did, before going mirophonic, even. They are 1976 Gibson Mini-humbuckers, which were known to go "mico" over time. The newer (both mini's and regular humbuckers) are (usually) already wax potted, but...not always. So, check that out, as well. Good luck! CB
epilover9568 Posted October 1, 2008 Posted October 1, 2008 elliot: I sent you a private message. Please read it. I think it will be helpful.
leicester35 Posted October 1, 2008 Posted October 1, 2008 Nice one' date=' I shall try all of that.And about my amp, Ive had it for about 4 years... Wait for it...

But that doesnt really count as a channel.[/quote'] Man, you're killing the tone of your beautiful guitar through that piece of rubbish! I know times are hard these days, but luckily you can now get really good amps for a reasonable price. Reckon a change might solve your feedback problem too...Heck, take your guitar to the music store to check out some amps - and kill two birds with one stone. If there's no feedback, then you've solved the riddle... Have a look at one of these: http://www.imuso.co.uk/ProductDetail.asp?StockCode=EG00273 or even it's more metal brother: http://www.imuso.co.uk/ProductDetail.asp?StockCode=EG01974 Amazing amps for the money. I've even gigged my AD30VT...and it held up just fine in a small pub...
guardian63 Posted October 8, 2008 Posted October 8, 2008 Hello everybody, I have just bought a epi black beauty 3, and I have a similar problem with it. When I place the switch in the rhythm I only hear big zummmm noise but not the sound of the strings, when I move the switch to the other two positions (middle, treble) I can hear the sound ot the guitar but with a lot of feedback noise, when I touch with my hand the humbuckers, the feedback noise desapear but when I play the strings again the feedback noise come back. If somebody has the wiring diagram I would like to have it, because I can't find it in the net. Please help me, and sorry for my english, I do my best. Thank you very much
