This BEHRINGER product has been designed to compete head to head with leading products on the market. We’ve included a status LED for effect On/Off and battery check, and you can run your DM100 on a 9 V battery or a DC power supply (not included). For absolutely noise-free operation, a first-class electronic On/Off switch is integrated. Crank up some hard-edged distortion without sacrificing the subtleties of your playing.
