I was a GK loyalist for 20 years and recently switched to all Ampeg (SVT Classic and 410hlf cabinets). VERY powerful and full tone for sure. I just found an old GK 800RB that was in a closet due to being broken down. I took it in and the amp tech figured out it was an internal fuse in the power supply. I never had a clue and after being stored for a decade I took it in to the jam room. I was shocked when I put the 800RB up against the SVT. It held its own pretty damn well. The SVT was a tad heavier in the low end, but the GK had a bit more punch. The GK has a very nice growl as well. In the end I had to run each head combined through its own 410hlf cab and that is GOD. I hate too many choices anyways. These two are my fave brands for years, but I really like the simplicity of the GKs. The SVT is fantastic, but the maintenance and weight and delicacy moving it are the downsides. I think I will be using the combo for a while though. I enjoy watching the looks on my bandmates faces when they ask "can you turn down just a LITTLE?"....
