Supro Analog Flanger

From the manufacturer:

HI-FI, MODERN FLANGER TONE

Sibling to the Supro Chorus, the Supro Flanger is an all-analog, full-stereo modulation effects pedal that uses a quartet of genuine MN3009 Bucket Brigade IC chips to deliver the absolute richest Flanger effect possible while maintaining exceptional headroom. In addition to Speed ​​and Width knobs, the Supro Flanger features a bi-directional Feedback control and a Sweep control that increases the delay time on one side of the stereo field while shortening the delay time on the other side. Featured for the first time in a flanger pedal, the Dimension switch crossfeeds the two channels into one another, creating the entrancing double-flange effect of two delay lines being modulated in opposite directions, even when used in mono. Runs on standard 9VDC.
