Hey everyone, After two months of waiting for a backordered 115, I finally got my new GK setup: 1001RB-II, 115RBH and 410RBH. I plug it all in at the store and it seems to work fine. The store is noisy though, so maybe I didn't notice the issue there. I take it home and set it up and immediately I notice: a) a steady, smooth hiss coming from the tweeters b) more of a buzzy noise that sounds like a grounding issue. The tweeter hiss I couldn't get to go away. The grounding buzz came and went depending on where I was standing in relation to the amp, and depending on the bass, if I touched the strings or not. Changing from the string-buzz bass, I switch to a different one, and now the buzz is there but touching the strings doesn't help, only touching the amphead makes a slight difference. Of course, the store is closed today so I can't call and ask them about it. What do you think? How much noise is common from this setup? Both the tweeter hiss AND the grounding buzz are driving me nuts.
