I bought my Kustom Groovebass 1200 new on ebay about 2 weeks ago. The silver and chrome front panel and blue power light are pleasing to the eyes. My first reaction was that it did not seem as loud as 1200 watts should be. After experimenting with numerous different gain and EQ settings, I finally hit on a sound that is really warm and punchy. And LOUD. It is so warm that I only need to use my BDDI now to add tubey distortion, although the Kustom does that pretty well too. The real mass of volume is at the high end of the knob, after 12. With my 2 ohm load, this thing DESTROYS guitars! The guitaist in my band plays thru a Marshall full stack, and this cuts through like a hot knife through butter. It is a little heavy, at 31lbs, but not too bad. It was a sweet deal at $520! Oh yeah, this baby is QUIET. No fan. You can't even tell it's on without the power lamp.
