First off, I love Ampeg. Always have, but I am looking at other options in my price range ($700-$1500). I could either go with the GK 1001RB-II or the SVT-3 Pro in the lower bracket of my price range, or I could go with the GK 2001RB or the SVT-4 Pro in the higher end of my price range. I need some serious opinions on these amps. As for the difference between the fact that GK is solid state and the SVTs are tube hybrids, I was planning on purchasing the Tech 21 Sansamp Rackmount to compensate for the GK solid state. I've looked into SWR and Eden. I am not impressed with SWR, and Eden is a little unknown to me as far as its sound is concerned. Thanks!
