Early advert for Guild's redesigned solid bodies of the mid/late Seventies. This advertisement was placed as early as September 1977, and as late as May 1978.
Guild used this ad format (guitar body, and headstock in the foreground) widely, however this is perhaps the only time it was not in colour. Compare with the corresponding ad for the dual pickup B-302A.
Throw away your ideas of what a bass should be like, because this is the one for now! Wide frets, curved fingerboard, Schaller M-4 machines, new pick-up, new solid brass bridge/tailpiece that gives you perfect intonation. Available fretless at no extra charge. Guild B-301: More than just a pretty bass. It's the first in a whole new generation of solid bodies by Guild.
