Is anyone familiar with these amps? I noticed that Nevermore uses them, and I love the sound that Jeff Loomis gets. I've been using solid state amps for a while, so I want to try to get a feel for what tube amps sound like, and the Kranks caught my attention. My friend suggested I get a Krankenstein or the Krank Revolution, but I want to know if its the worth the $3,000 price tag.
