Electro Harmonix Original Deluxe Electric Mistress Flanger. This is a mains powered model - so 240 volts. This is a classic if you want to recreate Hendrix sounds. This is a V1(version 1) from about 1978 - as the pots are dated 78 and most of the components. It is all original except for a UA741 resistor which has been replaced with a circa 1980 one. The pedal is in good condition for the year but not mint.
