the GK has that great, snappy, Solid State sound (I call it the Marcus Miller tone), and I love it...makes my Alembic, Spector and Fender basses sound better (to my ear) than any other amp

Tube preamp, and solid state

:In the end I was caught of guard with a solid state used GK RB1001-II in mint, unscratched, out-of-the-box condition and nabbed it at $400 after playing it through a Hartke VX410 (400 rms) together with a Hartke VX115 (300 rms) stack straight out as 700 watts rms at 4 ohms out to both cabs

For a solid state head, in this price range, I'm saying it's the BEST head on the market
