Unlike the Bi-Phase, which utilizes dual phasing, the Phasor 2X is more akin to a Mu-Tron II with an added channel, not a direct Bi-Phase reissue.

Mu-FX Phasor 2X Review - Premier Guitar

premierguitar.com

The Mu-Tron Mu-FX Phasor 2X delivers a nostalgic yet modern phasing experience, housing two distinct phasers in one compact design. Its vintage tones are lush and immersive, perfect for players seeking rich, analog character. The real-time control options add a dynamic layer, enhancing performance creativity. However, it requires a 12V power supply—leaving 9V users in the lurch—and lacks a battery option, limiting portability. Despite these drawbacks, the solid build and unique sound palette make it a worthy addition for phaser enthusiasts looking to capture that classic '70s vibe.

Mu-Tron's Phasor 2X is a nostalgic yet modern marvel that captures the essence of vintage phasing with an updated twist. Its rich, warm sounds and versatile controls allow for a wide range of tonal exploration, appealing to musicians seeking both classic and contemporary effects. However, the absence of series phasing and the necessity for a dedicated power supply might limit its appeal for some. Despite these drawbacks, the Phasor 2X stands out as a well-crafted, innovative pedal that promises to elevate any player's sound palette.

The Mu-FX Phasor 2X dazzles with its rich, vintage-inspired phasing capabilities and modern enhancements, including selectable 4 and 6 stage modes that expand its tonal range significantly. Its user-friendly controls and stereo functionality provide a lush soundscape, making it a formidable addition for any guitarist. However, while the pedal is powerful, some users may find the learning curve steep due to its extensive options. Overall, it’s a fantastic pedal for those willing to delve into its depths, offering both nostalgic charm and contemporary versatility.
