The Supro Analog Stereo Flanger is an all-analog, full-stereo flanger pedal, a sibling to the Supro Chorus in Supro's stompbox range. It uses a quartet of genuine MN3009 Bucket Brigade IC chips, the analog delay-line chips at the heart of its flanging circuit, and Pedal of the Day credits them with delivering "the absolute richest flanger effect"1.
Controls
The pedal's control set covers the usual flanger shaping plus the stereo-specific Sweep control1.
| Control | What it does |
|---|---|
| Speed | One of the two main knobs for shaping the modulation1 |
| Width | The second main knob, working alongside Speed1 |
| Feedback | A bi-directional feedback control1 |
| Sweep | Increases the delay time on one side of the stereo field while shortening it on the other1 |
| Dimension switch | Crossfeeds the two channels into one another for a double-flanger effect1 |
The Dimension switch
The Dimension switch is the pedal's distinguishing feature. Pedal of the Day notes it was "featured for the first time in a flanger pedal," and describes what it does: the switch crossfeeds the two channels into one another, creating what the reviewer calls the entrancing double-flanger effect of two delay lines being modulated in opposite directions, even when used in mono1.
Because the two delay lines are modulated in opposite directions, the effect does not depend on a stereo rig: a player running the pedal into a single amp still gets the crossfed double-flanger character1.
Sound and what reviewers said
Pedal of the Day, in a review presented with Sweetwater, describes the pedal as offering "rich, analog tone that strikes the tonal balance between vintage flanger units and more modern modulation effects"1. The reviewer also calls it "This deep purple beauty," so the enclosure finish is deep purple1.
Questions
Is the Supro Analog Stereo Flanger fully analog?
Yes. Pedal of the Day describes the Supro Flanger as an all-analog, full-stereo modulation effects pedal. Its flanging is produced by four genuine MN3009 Bucket Brigade IC chips, the analog delay-line chips that give the pedal what the reviewer called rich, analog tone, balanced between vintage flanger units and more modern modulation effects.
Does the Supro Analog Stereo Flanger work in stereo?
Yes. Pedal of the Day calls it a full-stereo pedal, and its Sweep control works across the stereo field: it increases the delay time on one side while shortening the delay time on the other. The Dimension switch crossfeeds the two channels into one another, and the reviewer notes that this double-flanger effect works even when the pedal is used in mono.
What does the Dimension switch do on the Supro flanger?
The Dimension switch crossfeeds the two channels into one another, creating what Pedal of the Day describes as the entrancing double-flanger effect of two delay lines being modulated in opposite directions. The reviewer notes it works even when the pedal is used in mono, and that it was featured for the first time in a flanger pedal on the Supro.
What chips does the Supro Analog Stereo Flanger use?
The Supro Flanger uses a quartet of genuine MN3009 Bucket Brigade IC chips, according to Pedal of the Day. Bucket Brigade chips are the analog delay lines that a flanger uses to create its swept, comb-filtered sound, and the reviewer credits them with delivering the richest flanger effect.
What is the Supro Analog Stereo Flanger's Sweep control?
The Sweep control increases the delay time on one side of the stereo field while shortening the delay time on the other side, according to Pedal of the Day. It works alongside Speed and Width knobs and a bi-directional Feedback control to shape the flanging effect.
