The Supercool Triniphase is an all-analog phaser from Canadian boutique builder Supercool Pedals, released on 27 June 2025 as the tenth pedal in the company's lineup12. Its circuit is based on the legendary Ross Phaser, but with many modifications and setting options, and it offers 4- or 8-stage phasing, two LFO modes, phase-based pitch shift, and a Dry Signal Bypass12. The enclosure is a nostalgic design inspired by the legacy of the Sony Trinitron, the classic television sets popular in the '80s and '90s12.
A Ross-based phaser with 4 or 8 stages
Guitar World's Alex Lynham describes the Triniphase as "based on the legendary Ross Phaser, but with additional functions"3. The original Ross Phaser was itself a 4-stage design, and the Triniphase keeps that option while adding an 8-stage mode for a deeper, more pronounced sweep. The red Depth toggle switches between them: 4-stage with the light on, 8-stage with the light off3.
In use, the two modes sit in familiar territory. Lynham found that "the 4-stage mode is reminiscent of classic phasers like the Small Stone, MXR Phase 90, and the Ross"3. The 8-stage mode pushes further, with Pedal of the Day's reviewer moving "easily from Untamed sweeps to Octo-Vibe tones to 8-Stage glory"1.
The maker positions the pedal as capable of a wide range of modulation, citing "unique sounds including classic phase sweeps, rotary-style univibe oscillation, formant-like voice effects, manic vibratos, and more"24. Pedal of the Day notes it does all this "while maintaining your volume and tonal integrity"1.
The controls
The Triniphase's control scheme pairs two knobs with a set of switches and toggles that can be mixed and matched for far more possibilities than a typical phase effect1.
| Control | What it does |
|---|---|
| Rate | Controls the sweep speed, spanning "glacial sweeps to frantic near-chaos"5 |
| Reso | Controls resonance, or feedback, from aggressive to subtle32 |
| Depth | Red toggle: 4-stage (light on) or 8-stage (light off)3 |
| Mode | Selects between modes, including the two LFO modes2 |
| BLUE/MODE switch | Activates phase-based pitch-shifting5 |
Guitar World lists the full control set as "Reso, Rate, Depth, Length, Mode"3, with the two front-panel pots handling resonance and rate. The BLUE/MODE switch is the gateway to the pedal's pitch-shifting mode, a phase-based effect that goes beyond conventional phasing5.
Uni-Vibe and vibrato sounds
For players chasing rotary and Uni-Vibe territory, the Triniphase can get close. Lynham found that "with the rate pushed up, there's decent vibrato and Uni-Vibe style sounds to be had" in the half-length mode3. That lines up with the maker's own description of rotary-style univibe oscillation and manic vibratos among the pedal's sound palette24.
What reviewers said
Guitar World's review was enthusiastic across the board, awarding the Triniphase five stars for both usability and sounds, and summarizing it as "an interesting feature set, great sounds and unique looks" at a "competitively priced" point3.
"Cheers to Jamie at Supercool Pedals on another gorgeous pedal release"1
Guitar Pedal X's Stefan Karlsson was similarly positive about the builder's track record, writing that "Supercool's designs are always incredibly appealing - both the aesthetic and the functional aspects - which always gives you more than most equivalent pedals"2.
Where it comes from
The Triniphase is designed and assembled in Canada by Jamie Muir of Supercool Pedals24. It is the company's tenth pedal, unveiled in late June 202514, and is available for purchase with worldwide shipping through SupercoolPedals.com as well as in select independent retailers4.

Questions
Is the Supercool Triniphase true bypass?
Yes. The Triniphase uses true bypass switching, so with the pedal off your dry signal passes through without the circuit coloring it. It runs on a standard 9V center negative power supply.
Is the Triniphase analog?
Yes. The Triniphase has an all-analog signal path and control, and is described as an OTA-based phaser effect. The phase modulation it produces is fully analog rather than digitally modeled.
Where is the Supercool Triniphase made?
The Triniphase is designed and assembled in Canada by Jamie Muir of Supercool Pedals. It is the tenth pedal in the Supercool lineup and ships worldwide through the maker's own site as well as select independent retailers.
Can the Triniphase do univibe sounds?
Yes. Guitar World's reviewer found that with the rate pushed up in the half-length mode there are decent vibrato and Uni-Vibe style sounds on tap. The maker also cites rotary-style univibe oscillation among the pedal's possible sounds.
What does the Dry Signal Bypass do on the Triniphase?
Dry Signal Bypass is one of the Triniphase's four main features alongside 4- or 8-stage phasing, two LFO modes and phase-based pitch shift. It lets you keep your original dry signal in the mix while the phased signal is layered on top.
