This range came in both bass and (proper) guitar variants, the basses being numbered KB-10, and the guitars KE-10.
The bodies were either solid ash (on the left) or mahogany and had a one-piece bolt-on hard rock maple neck with 22 frets.
The pickups were unbranded, so they were probably generic Japanese-made humbuckers of no special quality!
The controls were very simple compared to the switching options on other Kawai guitars. A 3-position pickup selector and a tone and volume control for each of the pickups.
At the time the catalogue was printed, the only finishes available were as shown. However, as you’ll see from the photos below, the Performer was certainly available in other finishes at some point in its life.
