The Caline CP-61 T-Drive Phase is a compact phaser pedal with an analog circuit. RockBoard's PedalPedia describes it as "a classic analogue phaser that gives you more control over your phased sound compared to the average old school phaser," and the extra control comes from three knobs rather than the single speed control many phasers offer1.
Controls
| Control | What it does |
|---|---|
| Speed | Sets the speed of the phaser's sweep1 |
| Width | Controls how big of a sweep the phaser produces2 |
| Feedback | Sets the chorusy depth of the effect2 |
Pedal of the Day summed the layout up plainly: "Width controls how big of a sweep and feedback is the chorusy depth."2 That arrangement is what separates the CP-61 from single-knob phasers: Speed sets the rate, and Width and Feedback then shape how far the sweep travels and how pronounced the phase effect becomes.
What it sounds like
Caline positions the pedal as covering a wide range of phased sounds: "Whether you want a slight movement in your lead sound or deep and watery phase sweeps for wide cleans, this tiny little" pedal is aimed at both ends of that range1. In other words, the same three knobs that give it extra control also let it sit behind a lead part or push a clean sound into deep, watery territory.
Pedal of the Day, reviewing the pedal in July 2023 alongside the CP-512 Old School Reverb, called the T-Drive "a phaser pedal with a wide range of tones" and concluded that "The CP-61 T-Drive Phase takes your phasing prowess up a notch"2.
Power
The CP-61 runs on 9V DC with a center negative plug and draws 30mA1. That is a light draw, so it fits alongside other pedals on a standard isolated supply without special arrangements.

Questions
Is the Caline CP-61 T-Drive Phase analog or digital?
It is an analog pedal. Caline describes the Phase as a classic analog phaser that gives you more control over your phased sound compared to the average old school phaser, with Speed, Width and Feedback controls shaping the effect.
What power does the Caline CP-61 need?
The CP-61 T-Drive Phase runs on 9V DC with a center negative plug, the standard pedal power supply arrangement. It draws 30mA, so a normal isolated pedal supply handles it, though a battery is not part of the specification given for the pedal.
How much current does the CP-61 draw?
Caline lists the current draw at 30mA. That is a modest figure by modern standards, so the pedal sits comfortably alongside other pedals on a standard 9V DC center negative power supply.
What do the Width and Feedback knobs do on the CP-61?
Pedal of the Day explains that Width controls how big of a sweep the phaser produces, while Feedback sets what they describe as the chorusy depth of the effect. Together with the Speed knob, they let you shape everything from subtle movement to deep sweeps.
