The Marshall AS80R is an 80-watt acoustic amplifier designed for amplifying acoustic-electric guitars and other acoustic instruments with natural, transparent reproduction. Featuring a dedicated reverb circuit and two channels optimized for acoustic pickup systems, the AS80R prioritizes clarity and a flat, uncolored response rather than the harmonic saturation associated with Marshall's electric guitar range. It was well received by acoustic players performing in medium-sized venues who needed reliable, feedback-resistant amplification.
