The new Mu-FX Phasor 2X is designed by Musitronics co-founder Mike Beigel, and features the same analogue electro-optical phase-shift circuitry as the original Mu-Tron Phasor II,  but with some new features and, Mu-FX say, a build quality in line with modern construction standards.



Housed in a mini-mu style retro enclosure with matching old school graphics, this updated version of the classic Mu-Tron Phasor II has been updated considerably for modern players. The pedal was shown at NAMM earlier this year and at the time they announced an ‘intention to buy list’ to gauge interest. But it is now available to actually buy, so was it worth the wait?

Multi-stage phase

The new Mu-FX Phasor 2 now has dual independent 4/6-stage phaser control sets and a stereo modified 5-stage output. The new modern hardware allows silent footswitches with true-bypass, plus an input for an external expression pedal, which can also be used for  CV control. The EXP toggle switches allow control of both the rate or sweep functions and so with no EXP/CV pedal attached, the Phasor 2X pedal can also become a stereo multi-pole filter EQ.

The pedal, of course, has stereo outs. Expect a swirling dervish of phase tones, hopefully with all those old classic phase tones on tap, but quieter in operation. The original Mu-Tron Phasor II pedals are still quite sought after and aren’t always in the best of shape and can be rather noisy. But this is what makes this new modern version appealing, as you can avoid all the niggles that can beset you using those original pedals.


It runs off of a 12V AC power supply, which is included in the price when sold in the USA, but you may have to fork out for one separately elsewhere, which is a pain. As it runs off AC, so if your power bank is a standard DC-only type you’ll need a dedicated additional AC output. There’s also the optional MU-XP2 Expression Pedal, so your total price can add up pretty quickly, but then originals aren’t exactly cheap either!


RRP – Mu-FX Phasor 2X USD 359.93  and optional MU-XP2 – Expression Pedal USD 160.00
