Pre-Owned 1975 Musitronics Mu-Tron Phasor II

The 1975 Mu-Tron Phasor II is a legendary American-made analog phaser that defines the sound of classic rock and studio production. Built with six phase-shift stages and three control knobs—Rate, Depth, and Feedback—this electro-optical marvel delivers lush, sweeping textures from 1Hz to 18Hz. Its AC-powered design provides exceptional headroom and a clean signal path (>86dB S/N ratio), making it equally at home with guitars, keyboards, or line-level sources. Heavy-duty steel and aluminum construction built to last. A timeless tone machine for players and engineers who demand authenticity.

The 1975 Musitronics Mu-Tron Phasor II is widely celebrated as one of the finest analog, electro-optical phase shifters ever created. Manufactured in the USA by Musictronics (Mu-Tron), this iconic pedal built upon the success of the original 1974 two-knob Phasor by adopting advanced, low-noise circuitry derived from the legendary Mu-Tron Bi-Phase. This pedla is in good condition and it's a vintage Mu-Tron!
