Maestro PS-1A Phase Shifter in very good condition with case.
Works flawless;y with a nice smooth ramping between speed changes.
Jimmy Page used one of these on "No Quarter".
Production Timeline: The original Maestro PS-1 was introduced in 1971. The revised PS-1A model (which addressed an input buffer issue to reduce popping) was manufactured and distributed between roughly 1973 and 1976
Serial Ranges: Early production runs of the PS-1A from 1973/1974 typically feature 4-digit and lower 5-digit serial numbers. The serial number (14138) falls into this early mid-run category, highly suggesting a 1974 assembly window
