I am selling my Ampeg SVT III Pro and opting for a power/preamp sound. I just got a Sunn 600W poweramp and am now looking for a decent TWO channel, RACKMOUNTABLE preamp. I really want a two-channel cuz, though 95% of the time play with fuzz, there are times when i need clean. I have been looking at The AMpeg Billy Sheenan model, but dont like some of the features on it. I thouht about a Sansmp RBI cuz i like their pedal version. Requirements for preamp; 1) channel switchable with separate eq's 2)tuner out and mute (optional) 3)2U of less. Thanks.
