An early and innovative example of a guitar synth system, this unit was designed by Tom Oberheim for Maestro. With a multitude of effects like a subharmonic octave, envelope filter, phaser, and wave form controls, this unit can create some otherworldly sounds like those heard on classic funk and soul records. This unit is in full working condition and all of the foot controllable effects sound fantastic! Perfect for guitar, bass, or key boards, this versatile unit is perfect for any studio. EXC $2,000.
