djohnson223 Posted May 30, 2015 Share Posted May 30, 2015 I am having a loud buzzing noise appear when I use a Relay G90 wireless system with the GK Fusion 550 head. I have tried three different Relay G90 wireless systems along with different guitars and still getting buzzing. I have took everything out of the rack to eliminate ground loops and have the amp and wireless plugged into the same outlet. I have tried at different locations (Warehouse and other House) and still have the same result, BUZZ BUZZ BUZZ. I have changed cables out. When I plug directly into the input of the amp I get no buzz. I have tried all the wireless systems on my other rigs and they have no issues, no buzzing. Dose anybody have any ideas why this is happening? Quote Link to comment Share on other sites More sharing options...
eklynx Posted June 1, 2015 Share Posted June 1, 2015 Have you tried the ground lift switch on the back of the head? Quote Link to comment Share on other sites More sharing options...

eklynx Posted June 2, 2015 Share Posted June 2, 2015 http://gallienkrueger.mivamerchant.net/manual/fusion-550-owners-manual/7/ switch #7. Granted it's for the direct out, but it's worth a shot. Quote Link to comment Share on other sites More sharing options...

djohnson223 Posted June 2, 2015 Author Share Posted June 2, 2015 I have even used a ground lift plug on the wireless and that made it worse. Quote Link to comment Share on other sites More sharing options...

ArneLine6 Posted June 2, 2015 Share Posted June 2, 2015 You could connect the G90 to another amp or just connect some headphones to the output to see if it is the G90 itself or some grounding issue when you connect to your setup.
