At Knobcon 2018, we talked with Mike Beauchamp from Therevox Custom Musical Instruments, who gave us a hands-on demo of his unique Therevox ET-4.3 synthesizer.

The Therevox ET-4 is a hand-crafted instrument that’s inspired by the Ondes Martenot, an instrument created by Maurice Martenot in the late 1920’s. The modern Therevox ET-4 line has been available for a few years now, and features three models.

Details are available at the Therevox site.

Here’s a behind-the-scenes look at how the instruments are made:
