Hey folks. I've been testing my new AC10 with my G5422 and am having some problems with hiss and hum coming through. Its amplified when I use my delay because, well...it echos. There's some hum with my SG, but much less, even with higher gain, so my guess is dirty power and interference with the Blacktops? I had a similar problem with my VT20x that I recently sold, only it was louder(!). Again, mostly muted with the SG. If I plug in the Katana, there's not much of anything. From searching around the forums, my guess is an issue with the power in the room. There's a dimmer switch, florescent bulbs, and my PC setup, which I use for recording. Any strategies for troubleshooting and eliminating the noise? Are there ways of filtering the power?
