Vintage 1970s Ibanez PT-707 Phase Tone II Phaser Guitar Effect Pedal - Blue With Original Box

This Ibanez PT-707 Phase II is a highly collectible vintage analog phaser crafted in Japan by Maxon during the mid-to-late 1970s. As part of Ibanez’s iconic "Wide Box Series," the PT-707 represents a major leap forward from the earlier single-knob Phase Tone circuit, introducing an expanded dual-control layout with dedicated Speed and Feedback parameters. Built around a classic Operational Transconductance Amplifier (OTA) circuit, this pedal delivers the lush, liquid modulation and organic, warm analog swell that defined late-70s guitar tones. Additionally, Maxon redesigned the input stage on the Phase II to significantly increase headroom, ensuring your signal remains dynamic, clean, and free from unwanted clipping even when hit with hot pickups or high-output boosts.

The inclusion of the variable Feedback control unlocks an exceptionally versatile sonic range, allowing you to feed a portion of the phased signal back through the circuit to generate intense, whistling pseudo-flanger sweeps and resonant, self-oscillating textures reminiscent of a vintage Small Stone or Mu-Tron. This particular unit is a late-70s Version 2 variant featuring the desirable block logo aesthetic, complete with its original 5-pin external DC power option and protective power cap. While the original silver knobs have been replaced over the decades, the internal analog circuitry remains fully intact, making this rare PT-707 a stellar addition to any vintage Japanese pedal collection or tone-obsessed pedalboard setup.
