VTG EF Johnson Intonation Trainer Keyboard


via this auction

"You are looking at a vintage E.F. Johnson Intonation Trainer.....37 Keys...really don't know much about this or what it is used for but it has a 1/4" Speaker out so I plugged it into my mixing board & it made some pretty crazy sounds. It seems like a synthesizer but not sure really. It comes in a hard case that has latches...it locks up but the handle you are suppose to carry it with is broke off."

    Would you be willing to see the intonation trainer?
