1976 Maestro Phaser
One of the original phase shifter pedals, designed by Moog and produced around 1976.
This is a vintage pedal in good working order. The exterior is extremely robust, if a little battle scarred. Powered with a 9 v battery only. Switching is by stomping on the whole pedal and is very effective, with controls being operated by your foot. Can also be used with bass. Probably the most ergonomic pedal you will ever find.
