Spectral Audio ProTone

“This is 1 of 20 Protones ever made with the gold faceplate. There is also a spelling error, instead of “RELEASE” it says “RELAISE”. These were made before the inventor founded his company Spectral Audio. This is a really rare piece of synth history. I took pictures with the top open to show the great condition of the internals. It is being sold as is untested because it is 230v and I don’t have a step down converter to test it.”
