amp buzzes when running stereo. what causes this?

[lancerontrack]

i am trying to run two amps threw my L and R outputs on my Boss GT-6. im really fine tuning my sound. i used to not bother me that there was a mild buzzing noise but now it does. i have played around with the ground lift switches and tried pluggin in differnt inputs on the amps, but it still buzzes. if i unplug on amp (doesnt matter which one) then it goes away, dead quite like its supost to be. i have tried more then just two amps and it still does it. amps i want to use is my Peavey Classic 50 and Ampeg Super Rocket. i even tried my 67' fender champ. most of the buzz is coming from my Classic 50.


any advice is much appreciated!

Sounds like groud loop between the efx and amps. Not between the amps.

ground lift adapter (3-prong to 2-prong) on the effects device. If that doesn't work, try using the adapter on one of the amps.
