RICKENBACKER produced the 450 COMBO between 1957 and 1984. The 1957 Combo 450 was the two toaster top pickup version of the Combo 400 and came in the same finish colors as the 400. Rickenbacker made several changes to the 450 over the years before finally discontinuing the model 1984. The 1957 Combo 450 had the tulip style body with neck-through-body construction. The two outer body wings were secured to the neck by two long bolts and glue. These first 450 Combos had metal pickguards, two controls and a rotary pickup selector near the lower horn. The rotary selector was soon changed to a conventional 3-way selector switch in late 1957. The body shape was changed to the cresting-wave style in 1958. An extra pickup became an option from 1962 to 1977. From 1966 onwards the 450 Combos had 4 controls.
