http://rvrb.io/2015-bc-1-bass-cru-8au The BC-1 Bass Crunch is a 2-channel JFET bass guitar preamp / DI from AMT Electronics, that provides a wide variety of bass guitar sounds: from clean and transparent to slightly compressed overdrive to modern thick distortion. Featuring 3 (three) outputs, the BC-1 can be used either with a bass amplifier's power amplifier or directly with an audio interface or mixing desk/PA, thanks to its built-in cabinet simulator! Controls include separate 3-Band EQ (HIGH, MID, LOW), GAIN and LEVEL as well as MIX knob in order to allow the player easily dial in the ideal blend of detailed overdrive and clean sounds with massive low end.
