1974 vintage Elextro-Harmonix Frequency Analyzer pedal. Made in USA. Power chord included. In excellent (near mint) condition. Hardly used. One owner. I purchased this pedal with plans to use it for a horn (trombone). Played through a microphone, I could not get the sound I had hoped for. Tested today with an electric guitar and it functions perfectly. Never disassembled, never modified.
