No matter then.
What is powering those pedals??

Re: help me shut my amps up...
Dig it. You can't get a ground loop between two amps like that. But if you were running two heads at the same time you'd have to lift the ground on one amp either at the power or the audio input to break the loop & cure the noise. Amp switching rigs are a whole other thing & invite certain "problems" or circumstances...
Anyway...getting a Furman box like a PL-8 won't do sht for 'ya. If you can lift 15 or 20 amps of "power conditioning" with one hand then it's not "power conditioning". Generally you need HUGE heavy transformers to accomplish that task. You'd have to at least get the line regulator one to get anything more then a glorified power strip. The AR115 or 117 or some such is the "bottom barrel" regulator. About $500 IIRC.
Some conditioners use other electronic means to clean AC power rather then a transformer. I've got a Monster 3500 feeding all the audio gear in my mix room but that isn't without its own problems. It actually increased the noise floor in the room by small amount.
But, it DID cure one really weird specific problem that was wreaking havoc on the place. For some reason, even though the computer was on it's own circuit and a UPS...it was spewing all kinds of hash back into the line which was affecting A LOT of other equipment in the room...most notably the console!
Interestingly enough...when I plugged only the console or only the computer into the Monster thingy the noise was EVEN WORSE! But if both were connected then all was/is well.
AC power is some weird voodoo stuff. Don't let the little noises bug 'ya...that'll drive you nuts. Be willing to accept some noise.

Re: help me shut my amps up...
i found it...the majority of it is due to the stupid George L's cables on my board. i did a sloppy rewire using full length guitar cables between the pedals just to test it and the majority of the noise is gone. a decimator pedal should kill the rest and i'll be good to go.

Re: help me shut my amps up...
i foolishly never thought to check the board wiring at full volume since i finished it late at night and since it's been done it's only been used at low volume and not often (i use my atomic 1x12/podXT setup more) so when i got to crank my amps today i heard the evil hum.
J: thanks for all the info but it seems it was a false alarm and mostly caused by my pedal board. :smack: i think i'll still invest in a decimator pedal down the road after my board is rewired since it can't hurt.

Re: help me shut my amps up...
some people have great luck with george L's but as i think about it several of the guys that have good luck are NOT high gain players. so the fact that the cable is given power by just touching a metal pin to a wire with no solder joint and a ground is just a metal cap that cuts into the wire to hit the braid doesn't matter. however when you start to move into high gain areas where you are actually creating more wanted "noise" with the amp this method of connection IMO is not good enough and you need a nice solid soldered ground and power on the cables to keep noise down. when i play on the clean channel with my board wired as it is with the george l's i get NO noise at all and even at a moderate blues or light rock type gain it has very little hum. once i go into my normal tone with gain at 12 - 1 o'clock on the peavey, the dual recto or the powerball the hum is there. again this is just my opinion and thoughts on it. but i'm ditching the george L's once and for all. i've given them 4 tries and had nothing but crap luck with them.

Re: help me shut my amps up...
cool thing you found the source for the noise, bad for you that you'll have to buy expensive new cable now. I was rather surprised that you were getting that much hum with a Powerball since this amp has one of the best integrated noisegates i can think of(at least the newest edition ,to which mine belongs does. I think they tweaked the NS).
If you want a good gate and if you can live with a pedal you should keep your eyes open for one of the old USA made hush pedals. They were two channels with two different treshhold settings(very cool if you are switching gain levels) and imo it works better than the NS-2(the new korean hush pedal sucks btw). haven't tried the ISP.
