SIGMA BMC-155E Fivestring Acoustic Bass


Acoustics for stage use Five-string

With the BMC-155E Simga presents a stage-suited acoustic five-string at an incredible price/performance ratio. The mahogany dreadnought body provides a warm sound with powerful low-end and clear treble for accompanying grooves and solo work. The solid ceiling promises lively dynamic reserves that support expressive play.

The Fishman Isys+ pickup system captures the sound of the Sigma BMC-155E with natural dynamics and warmth across all strings, making it easy to pick up on stage or in the studio. The phase reversal switch helps to suppress any feedback that may occur, while the 2-band tone control allows you to adjust the sound for bass and treble. In addition, the integrated tuner ensures that the BMC-155E is always in perfect tune.
