The Retro-Sonic Classic Analog Flanger is an analog flanger pedal from Canadian maker Retro-Sonic. It is controlled with a single Normal/Effect footswitch, and its small footprint measures 4.4 x 2.3 x 1.1 inches1.
The controls
The pedal carries five controls on its face: Rate, Range, Level, Color and a Filter Selector, plus a Normal/Effect footswitch2. The layout follows the Electric Mistress, which pairs its flanging circuit with filter-based voicing options, and Pedal of the Day's review also noted an LFO toggle on the pedal3.
| Control | What it is |
|---|---|
| Rate | Speed of the flange modulation2 |
| Range | Depth or span of the modulation2 |
| Level | Output level2 |
| Color | Tone shaping, carried over from the Electric Mistress layout2 |
| Filter Selector | Filter voicing selector switch2 |
The Normal/Effect footswitch takes the pedal in and out of the flanged signal2.
Power and connections
The Flanger runs on a 12-18V negative pin adapter, matching the higher voltage supply the original 18V Electric Mistress design used23. Input and output are both 1/4-inch standard phone jacks2.
The pedal is a compact unit, measuring 4.4 x 2.3 x 1.1 inches, with a single Normal/Effect footswitch1.
Availability and recognition
Retro-Sonic paused and resumed production of the Flanger in recent years. On June 25, 2024, the maker announced it was again taking orders, with shipping approximately 3 to 5 weeks from order placement2. The current version is newly redesigned with black powder-coated sides2.
The Retro-Sonic Flanger's compact size, at 4.4 x 2.3 x 1.1 inches, puts it among the small-footprint flangers a player can fit on a crowded board1.

Questions
What does the Color knob do on the Retro-Sonic Flanger?
Color is one of the four knobs on the Retro-Sonic Flanger, alongside Rate, Range and Level. The pedal is a compact recreation of the 18V Electro-Harmonix Electric Mistress, and Color carries over the tone-shaping role that control has on that circuit. Pedal of the Day's review lists it among the pedal's controls together with an LFO toggle and an analog BBD signal path.
How much does the Retro-Sonic Classic Analog Flanger cost?
Retro-Sonic lists the Classic Analog Flanger at US$199.00 on its product page as of October 2026. The pedal was announced at the same $199 price when Guitar World covered its launch in July 2019.
Is the Retro-Sonic Flanger available to buy again?
Yes. On June 25, 2024, Retro-Sonic announced it was again taking orders for the Flanger, with shipping approximately 3 to 5 weeks from order placement. The current version is newly redesigned with black powder-coated sides.
What does the Filter Selector do?
The Filter Selector is a switch position on the Retro-Sonic Flanger's control panel, listed by the maker alongside the Rate, Range, Level and Color controls. The pedal follows the layout of the Electro-Harmonix Electric Mistress it is modeled on, which pairs its flanging circuit with filter-based voicing options.
