The original Acoustic Blender is ideal for mixing an internal microphone and pickup together on guitar, cello, violin, mandolin, harp, banjo and other acoustic instruments. This unit offers two independent channels, each with volume, bass, treble, phase and input trim controls, plus a full complement of stereo and mono inputs. The Blender’s rear panel includes three effects loops and three sets of balanced/unbalanced outs for just about any signal routing scenario imaginable. A master volume control, headphone out and mute switch round out this powerful feature set. The Acoustic Blender operates on a 9-volt battery, or an optional AC power supply (not included).
