Production of the ELECTRO SPANISH began in 1932 and ended in 1935, when it was replaced by the Ken Roberts Electro Spanish model. This model had a flat topped hollow maple plywood body and mahogany neck, both made by Harmony. It had a single horseshoe pickup but at first had no controls. In 1934 a single volume control knob was added, as well as body binding. The classical style slotted headstock had a pearl veneer, with a silk screened "Electro" logo on the earliest models or a metal nameplate with the pre-war "Rickenbacher" spelling. The Electro-Spanish had two highly placed f-holes like on the National Trojan (also made by Harmony) - these were moved lower down on the later Ken Roberts model.

This model should not be confused with the solid body bakelite Electro Spanish Model B. Rickenbacker also produed the Rickenbacker Spanish model (SP) from the mid 1940s until 1950.
