The SC-450s were made in Japan by Matsumoku from 1976 to 1979.
The SC-450 has a three piece maple body with a scroll on the upper horn and a German carve around the body. The set neck is also three-piece maple with an ebony fingerboard, dot inlays and brass nut. Scale length is 25.5 inches, and the fingerboard width is 1-11/14 inches at the nut. The 24 fret neck joins the body at the 21st fret.
Hardware is chrome plated including a fully adjustable tune-o-matic bridge and stop tail-piece.
Pickups are two exposed or covered coil humbuckers (depending on pickup options), controlled by a three position toggle switch and single volume/tone controls. There is also a coil tap switch.
Finish options were walnut stain or natural.
There was also the option to have Gibson humbuckers on the SC-450. The models with the Gibson pickups wasthe SC-450-G. These Gibson buckers had inductance of 8.6 Henries, a resonant peak of 6.0 KHz and DC resistance of 16 K Ohms. They had dual exposed black bobbins (with a T on the top), 12 adjustable gold plated pole pieces and copper-wrap shielding/grounding.
