The Rickenbacker M-8E is a late-1950s variant of the M-8, distinguished by an external speaker jack or revised cabinet and speaker specification. Its tube circuit is fundamentally similar to the M-8, maintaining the warm, compressed single-ended character of the original. The revision reflects Rickenbacker's incremental product refinement during a period when the company was building its reputation as a maker of both guitars and amplifiers. These amps are occasionally paired today with vintage Rickenbacker guitars for a period-correct California combo.
