Established in Kalamazoo in the early 1970's as Systems & Technology in Music, Inc, SysTech was a pioneer in guitar effects. The company was founded by Charlie Wicks, who would later go on to found Pro-Co, and Greg Hochman, who was Keith Emerson's Moog tech. This mid-70's 4-stage phaser features separate rate controls with a footswitch to swap between the two on the fly, an emphasis knob which controls feedback, and runs on 9v! This specific example is missing the screw for the front battery compartment. Get this piece of guitar history today!
