Or a solid state stereo preamp that would do well as part of a modular stereo rig? I play bass more like metal guitar (I'm a guitarist who prefers bass frequencies, fatter strings, and bass gear, go figure) and run: Bass -> Fulltone Bassdrive -> Amp Recently I discovered thru headphones running the Bassdrive to something called a Yamaha UD Stomp modulation device can yield a MASSIVE distortion sound field that I would like to get out of the headphones and into the atmosphere at large. The ideal would be Bass -> Bassdrive -> UD Stomp -> ??? -> 2 identical cabs acting as "left" and "right" UD Stomp has two 1/4" outputs so I just need to fill that gap in the chain with one magic box or a magic stereo preamp running to something like a QSC power amp. I did every conceivable search related to stereo rigs on the forum here and all I came up with is the Alembic F-2b. Got to be more options out there. I would be so thankful for any help, this sound is too good not to pursue.
