I had this same problem but got it figured out. The problem is the level that you are sending out is just plain too hot. You need to back off on the output level. Let the FOH board create the gain. Try that and see if it works out for you.I just picked up as new Liverpool today to run my M13 through. When I fired it up it made alot of buzzy noise. Even when I just ran it direct without the M13 into my PA. Anyone else have similar experiences and what did you do to correct it? Thanks
I think this may have been most of the issue. I thought I had it far enough but I guess not. The other part of the issue I'm suspecting is P90 pickups. Thanks for the input guys. Very helpful.My Liverpool is quiet when it's not close to my M13 power supply
cheers
