How do you fellas get around this? Even when I run my amps OD channel pretty quiet, theres still a feedback, obviously more noticeable when I'm not playing.

I've never gigged but I cant imagine what some of you guys would have to do to stop that excessive noise when you're running a half stack flat out. I have a Boss NS 2...kinda kills the tone though.

Marshall AVT 50 with a Highway 1 Tele.

Paul, how many overdrive/distortion boxes are you using? I use the same amp with a Tele for gigging and I don't have any feedback problems, but I'm just using the Marshall's overdrive for distortion sounds and only use effects boxes for delay, chorus, or tremolo sounds.

Single coil pickups are sensitive to ambient RF noise. There are some mitigating measures you can take - shielding, for example - which can help, but as long as you are running vintage style single coils, especially through a lot of gain, you are going to have some hum.

Noise gates help when you are not playing, but they can't filter hum out of your sound while you are playing.

I assume from your screen name that it is a Tele you are dealing with. You can get a RWRP (reverse wound reverse polarity) replacement pickup for one position, and then at least when you play with both of them on, you have humbucking.

Noiseless pickups and mini-humbuckers are available, but they compromise the tone; if what you want is that glassy vintage single coil sound, then you might not be happy with what they give you.

You might look around at your environment and see if there are any RF sources you can get rid of or get away from. Computer monitors, fluorescent or neon lights, TV sets, refrigerators even your tube amp, all have motors or transformers which emit RF hum. Also, try moving around and standing facing different directions; sometimes a RF field is planar and will affect your pickups less if you hold your guitar perpendicular to it.

Good luck; I feel your pain. There is a set of medium tension power distribution lines that run along the side of my property right outside my studio, and I have a pretty major 60 Hz electromagnetic field from it. When I run my Strat with a lot of gain I have to face a certain way not to have ton of hum.
 
Yeah, just move around and find the spot where it doesn't hum. You could buy hum-canceling pickups, but that gets pricey if you're on a budget. I don't record often with my strat, but when I do, I have to find the sweet spot to kill the buzz. I usually have to have the guitar perpendicular to the imaginary line running from my amp to my computer monitor. It's goofy, but it works. I've shielded my strat per the instructions posted in that link - I followed them precisely - but it didn't help much. It did help some, but not enough to warrant the amount of work required to do it. I had to go in there to fix a switch and some wiring, so I did it since the guitar was gonna be apart anyway.

Or, you can just buy something with humbuckers and rock on - quietly. :p
 
yeah I knew what I was getting into with single coils....just annoying...guess I'll move around my room and see what happens. Tony, I do use boxes but its there even when I dont.

I wonder if what you are calling feed back is a microphonic tube in the AVT50's preamp? That may be a possibility Paul, if I recall I think the amp is a closed back and I've never opened mine up so far, a bad tube will do some wacky stuff though.

well feedback...by that I mean, when I stop playing the amp hums...which I know is par for the course for single coils. But when I have it on OD, it hums like nothing else!

Well, you might consider a noise gate. The thing is, though, that you'd have to set the threshold fairly high to kill the hum when you're ODing, and that will chop off your notes as they decay. The other thing you can do is be quick on the switch when you stop playing.

Have a gate, and its good alright, but it does cut the attack from the high notes.

Yeah, well, there you are. Gates are a definite tradeoff.

Same experience here. That looks like the site I used to shield my strat and I did'nt really notice any difference in hum/buzz while being around a crt monitor. Get a lcd monitor.
