An all-analog, full-stereo modulation stompbox that uses a pair of genuine MN3007 Bucket Brigade IC chips to deliver the thickest, most luscious Chorus effect possible in pedal form, all while maintaining exceptional headroom. In addition to Speed and Depth knobs, the Supro Chorus features a Time control that increases the delay time on one side of the stereo field while shortening the delay time on the other side. Further increasing the available drama is a Dimension control, which mixes the stereo channels into one another for a mesmerizing intermingling of the two delay lines being modulated in opposite directions. A Vibrato switch removes the clean pass-through signal, allowing for pure pitch modulation with the Dimension knob, introducing a more complex, double vibrato effect. Runs on standard 9 V DC.
