– Mu-Tron Biphase –

The Mu-Tron Phasor II (Phi-Phase) is a rare and highly regarded analogue phaser from the golden age of studio effects. Known for its rich, organic modulation and unmistakable vintage character, it has become a sought-after processor among musicians, producers, and collectors looking for the classic Mu-Tron sound. Its warm analogue circuitry produces deep, musical phasing effects that remain unique decades after its introduction.

Technical

* 220V European version.
* Fitted with a standard European power plug.
* For use in 110–120V countries, a simple and inexpensive external step-up voltage converter is required and can easily be found online.
* The unit has been serviced overall.
* The first channel has a permanent background noise. Although the phasing effect is present, the noise makes the channel impractical for normal use and it should be restored. The unit is therefore currently fully usable in mono via the second channel. The second channel operates perfectly.
* The unit has been modified to operate continuously without the original footswitch. This is a simple, fully reversible modification: removing a single solder joint restores the original footswitch operation. For studio use, this modification is particularly convenient.
* Sold accordingly.

Condition
* Good cosmetic condition for its age.
* Front panel is in good condition.
* Visible scratches and minor signs of wear.
* Please refer to the photos for the overall cosmetic condition.
