The Deluxe version of the Memory Man delay pedal from Electro-Harmonix debuted around 1977. As of 2024, It’s still (or again) in production, with a basically unchanged design.
The pedal name is set in VGC’s Barry and a bold condensed sans, possibly Kabel Black with straightened terminals. Labels are in Helvetica and sometimes also in Futura. The Electro-Harmonix logo is set in Skjald, see the dedicated post.
