Saturday Synth Porn: The Wersi Delta Digital DX500T Glas was a transparent Lucite organ, made in 1987 by Wersi Electronics.
While this sexy beast may look like it belongs in the lair of Bond villain, it is a prototype that was used as a display model. There were only 2 examples in the United States.
This instrument went up for auction a few years ago.
From the auction description:
The Delta Digital DX500T Glas organ comes replete with all manuals, control panel templates, music stand, T5100 amplified speakers, Lucite dollies, pedal board, adjustable bench and chromed keys. And it works beautifully!!!
