I am running my Alembic F1-X into my GK 700RBII. I use the effects loop and totally bypass the GK. It is a great rig for the most part running into either one or two SWR Goliath's depending on the gig. The one issue I have is that nearly on every gig I feel the power start to drop. I still have a signal but I am getting no push. It is like the bottom drops out of my sound all together. The first time I had the problem it was really bad and my volume was almost nill. I switched to the GK and it was fine. Then I realized that the the power chord on the Alembic was loose. I pushed it all the way in and it was fine. So I was thinking that maybe I needed a new power chord for the Alembic. But now I have found that when it happens and I am in the middle of a gig....if I shut the power down to the whole rig and power it right back up all is fine and I can finish the night. This make me think it is not the power chord.....I am very perplexed now as to what could be the problem. Any ideas?
