These plastic 'bell' control knobs were fitted to almost all electric guitars produced at the Matsumoku guitar factory, Matsumoto Japan from the mid/late 1960s to the mid 1970s. All were painted from the inside, with an (approx) 7mm clear section, and a gold metal reflector cap marked V (volume) or T (tone). It seems these knobs were solely used by Matsumoku, and are a very good indication of a Matsumoku-made guitar. Three colours exist: gold and silver (with black numbering) and black (with white numbering). Not to be confused with other similar looking vintage Japanese guitar knobs without the metal cap. more
