This is a vintage 1976 Ibanez Phase Tone II “PT-707” electric guitar phaser effects pedal. This particular ‘Made in Japan, Pat. Pend.’ example is in very excellent condition and includes the original box! The completely script type face around the on/off button indicates that this is the first, and more coveted, version. This is a fantastic sounding analog phaser that attractively emulates a subtle Leslie effect.
