Hi guy's, I recently (1 week ago) bought a new Fender Mustang GTX100 Amp. I'm very happy with it. I also have a Fender HotRod Deville 4X10 but its a bit heavy to lug around and a bit big for small venues hence the GTX. I use a bug type wireless system with my Telecaster and have no issues with it plugged into the Deville, but when I plug the bug into the GTX it sounds like I have a phaser in the line. This doesn't happen with the Deville, I tried a different wireless system but get the same result. Anyone had this issue? Does anyone know how to fix it? I don't want to go back to a lead as I usually am out front of stage for the first couple of songs fine tuning the PA with my guitar on so I know what level it's at. Any help would be appreciated. Cheers Bunji.
