just picked one up and this thing is easily top 3 amps I've ever played! I typically play and Ashdown ABM500 but I've also owned Ampeg SVT 2, 3, 4 and CL as well as well as GK 1001RB and MB Fision 800. I've played about every amp that's out there over the past 15 years and I was blown away by this thing. SO simple! Master volume, treble, mids, bass. Having said that its VERY versatile! Also has a 2nd channel that can be engaged via FS. The channel is engaged WITH channel 1 and has 2 knobs....blend and grit. It can go from mild tube like grit to full blown chaos distortion. Can't say enough good things about it! Oh and power for days!!!!!
