The BSX Bass Allegro 5-String acoustic-electric upright bass is the best of both worlds. For tone, you get the depth and ring of an acoustic upright bass, with extremely flexible electronics. The multi-sensor piezo bridge system coupled with active circuit Bartolini electronics sounds extremely realistic both pizzicato and bowed. BSX Allegro Series feature a 3-band EQ, on-board preamp, and an individual volume control for each string. For looks, you get one of the coolest hybrids of classical styling and modern technology you've ever seen!
