Every effect a bass player could ever need (except of course Wah-Wah) in one compact box: distortion channel with gain, volume and blend controls; noise gate switch with trigger control. The clean channel features a colour switch with bass, mid and treble controls. Powers up via battery adaptor or phantom power from your mixer. Phantom power switch doubles as a ground lift. Buffered bypass. Powered by 9 volt battery or AC adaptor.
