Jon Johnson Report post Posted April 1, 2017 The Hillwood RB-1 is a remote controller keyboard made in 1977 by the company Hillwood and it's design said to be influenced by Edgar Winter. The instrument is considered to be one of the first Keytar instruments. Its simple design of a piano with a voltage controlled filter allowed the player to make synth type sounds while having it strapped on like a guitar. The front panel offered a limited set of controls with knobs and a a switch lever. View full synthesizer Share this post Link to post Share on other sites
