Yamaha FS Keybed
Installing Keys & Fixing Contacts

This keyboard assembly, or keybed, was used in many high-end instruments sold by Yamaha and Korg. The keybeds aren't usually interchangeable between models, however, because of variations in the key switch circuits, the after-touch, and the mounting details. The keys themselves are interchangeable, however, and the key switches work the same.
