The Supercool Pedals Triniphase is an all-analog phaser pedal from boutique builder Jamie Muir of Canada's 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 additional functions layered on top: switchable 4-stage and 8-stage phasing, two LFO modes, a phase-based pitch shift mode, and dry signal bypass13.
The look is as distinctive as the circuit. Premier Guitar describes an eye-catching nostalgic design inspired by the legacy of the Sony Trinitron television, part of what the announcement called a cassette-futurism aesthetic4.
What it does: a Ross-based phaser with 4 and 8 stages
At its core, the Triniphase is an all-analog OTA-based phaser effect based on the legendary Ross Phaser pedal, but with many modifications and setting options2. OTA (operational transconductance amplifier) phasers use voltage-controlled stages to sweep notches through your signal, which is the same approach behind many classic phase pedals. Guitar World's reviewer, Alex Lynham, found the 4-stage mode reminiscent of classic phasers like the Electro-Harmonix Small Stone, the MXR Phase 90, and the Ross itself1.
The switchable stage count is the headline feature. The red Depth toggle moves between 4-stage phasing (with the light on) and 8-stage phasing (with the light off)1. Four stages give the quicker, more vocal sweep associated with those classic pedals; eight stages give a deeper, more dramatic sweep. Pedal of the Day describes the range of the pedal's character:
"Moving easily from Untamed sweeps to Octo-Vibe tones to 8-Stage glory to just complete Wow2!"

Beyond straight phasing, the BLUE/MODE switch activates a phase-based pitch-shifting mode46. Premier Guitar's announcement lists the palette the pedal can reach: classic phase sweeps, rotary-style univibe oscillation, formant-like voice effects, manic vibratos, and more4. Guitar World's reviewer found that at more extreme settings, there is pitch modulation and strange ring-mod artifacts1. Pedal of the Day also notes the pedal maintains the volume and tonal integrity of your instrument while doing all of this2.
The controls
The front panel holds two pots and three switches, which Pedal of the Day sums up as three buttons that can be mixed and matched for far more phasing possibilities than a typical phase effect12.
| Control | What it does |
|---|---|
| Rate | Sets sweep speed, spanning glacial sweeps to frantic near-chaos16 |
| Reso | Sets resonance, or feedback, intensifying the sweep's character1 |
| Depth (red toggle) | Switches between 4-stage (light on) and 8-stage (light off) phasing1 |
| BLUE/MODE switch | Activates the phase-based pitch-shifting mode46 |
| Length | Selects the phasing length, with the half-length mode opening up vibrato and Uni-Vibe style sounds at high rates1 |
Guitar World's control list names the full set as Reso, Rate, Depth, Length, and Mode1. The two LFO modes are part of the pedal's feature set alongside the 4- and 8-stage phasing and the dry signal bypass3.
What reviewers said
Guitar World's Alex Lynham reviewed the Triniphase in 2026 and gave its sounds a five-star rating, calling it competitively priced at its $219 launch price1. His overall verdict:
"An interesting feature set, great sounds and unique looks"
Guitar World, Alex Lynham, 20261
On versatility, he was more measured:
"Like a lot of options out there, it's good for a few go-to sounds but it's a pedal that rewards enthusiastic phaser fans"1
Guitar World, Alex Lynnam, 20261
He also found that at more extreme settings, there's pitch modulation and strange ring-mod artifacts1. Pedal of the Day's reviewer cheered "another gorgeous pedal release" from Jamie at Supercool Pedals2.
Where it comes from and where to get it
The Triniphase is designed and assembled in Canada by Jamie Muir143. It is available for purchase with worldwide shipping through www.SupercoolPedals.com as well as in select independent retailers4.
The Triniphase runs on a standard 9V DC center negative power supply14, so it fits a typical pedalboard power brick. No battery operation is mentioned in the product information.

Questions
Is the Supercool Triniphase true bypass?
Yes. The Triniphase uses true bypass switching, so your dry signal passes through untouched when the pedal is off. It runs on a standard 9V DC center negative power supply rather than a battery.
What does the Length switch do on the Triniphase?
The Length control switches the phasing depth of the circuit. In its shorter setting the pedal runs as a 4-stage phaser, and in its longer setting it runs as an 8-stage phaser, giving you a subtler classic sweep or a deeper, more dramatic one.
Can the Triniphase do univibe sounds?
Yes, according to Guitar World's reviewer. With the rate control pushed up in the half-length mode, the pedal produces decent vibrato and Uni-Vibe style sounds. Pedal of the Day also describes Octo-Vibe tones among its possibilities.
Where is the Supercool Triniphase made?
The Triniphase is designed and assembled in Canada by Jamie Muir, the builder behind Supercool Pedals. It is the tenth pedal in the Supercool lineup and ships worldwide through the Supercool Pedals website and select independent retailers.
Is the Triniphase analog?
Yes. The Triniphase has an all-analog signal path and control, built on OTA-based phaser circuitry derived from the legendary Ross Phaser, with additional functions layered on top of that classic design.
