The Electro Harmonix Electric Mistress Flanger/Filter Matrix, designed in 1975–1976 by David Cockerell, was the first ever flanger to be made in a pedal format.
This particular version was available between 1976 and 1981. “Flanger/Filter Matrix” is in ITC Serif Gothic. Knob labels are in all-caps Futura. The Electro-Harmonix logo is in Skjald, see the dedicated post.
Note: The unidentified type of the main Electric Mistress logo remains something of a mystery. Upon checking various forums, it's been hypothesised that this typeface is either custom lettering, or a modified version of an existing type such as DeCoro or similar.
[Edit: it’s Raflo, see comments.]




The Deluxe Electric Mistress was offered along side the original Mistress between 1978 and 1981 and later reissued in 1999, and now is discontinued.
