Lifted straight from our popular OB1 Series amps, the Blend and Gain controls are a nod to the many bass players who experiment with guitar and bass amps simultaneously. In this ‘bi-amped’ setup, layers of harmonics and distortion from the guitar amp are blended with the core bass tone to create the ultimate full-range live sound. The Crush Bass 50’s Gain and Blend controls create the same effect in a single package, adding extra bite and crispness to the tone at lower gain settings, right up to all-out filth with the dials cranked. These controls can also be engaged remotely with the optional FS-1 footswitch, ideal for fattening your tone on the fly.
