PT999

The Maxon PT999 Phase Tone pedal is a compact and versatile phaser unit designed for guitar and bass effects. It offers a range of authentic 70's era phasing effects in a current production unit. The PT999 features a minimalist circuit with a single knob and switch, allowing for a wide variety of expressive phasing nuances. The circuit used in the PT999 is unchanged since its introduction in 1974, providing a timeless tone.

The PT999's four-stage phasing circuit offers 720 degrees of phasing sweep variable from 0.2 to 14 Hz. The FET's (Toshiba #2SK246) are carefully sorted and matched by hand to produce a smooth phasing sweep with low noise. The pedal runs negative feedback of the signal to each phase-shifting FET for less distortion. Internal trimmers adjust center frequency and width of the phasing sweep, calibrated prior to market.

The PT999 Phase Tone pedal is designed to provide classic phase shifting effects without compromising the guitar's signature tone, making it a valuable addition to any musician's effects arsenal.
