Be sure to add me to your favorites list 1980's Vintage Casio VL-TONE / VL-1 Mini Keyboard "Octave" "Tones" "On/Off" Selector Knob Replacement Part. This is a SELECTOR sliding knob part from a 1980's era VL-1 VL-TONE Casio mini keyboard. This part was used to select the Octave, the Instrument tones, and On / Off switches on this very small collectable keyboard. Unfortunately, these are very easily lost, so here's a replacement if you needed one! This part is a SELECTOR knob, used for the stems that select the octave, the instrument sound, and the play / record / off buttons ONLY. THIS IS NOT THE CORRECT PART TO USE ON THE VOLUME OR BALANCE. They look similar but they will not fit those stems. This one is in very good condition, and I have several of them available. Thanks for looking, Check out my Store!
