The Magnatone 26R is a mid-1960s combo that adds onboard reverb to the established Magnatone formula. The spring reverb provides a warm, diffuse wash that complements the pitch-vibrato beautifully, producing a distinctly dreamy, surf-adjacent character. The R-suffix designation indicates the reverb option, which was added to several models as the surf era drove demand.
