Analog Phaser pedal with Tone Lok function.
A classic from the Grey Years of Ibanez - the Tone Loks with their "Locking" parameter controls.
With a Push of the Knobs, you can lock them in place.
This Used pedal is in Very Good Condition with some cosmetic wearing - as seen in the pictures.
Can be powered by a 9 Volt Battery or Boss Style 9 volt adapter (not included)
