The Rare Tuttivox by Harald Bode
video upload by HAINBACH
"I have been very interested in the work of German inventor and engineer Harald Bode. His essays and instruments were hugely influential on Robert Moog, Don Buchla and many others, and laid the ground work to the synthesizers of today. Sadly, most of his more experimental designs don't survive. But some of his more conventional instruments do, like his adaption of the proto-synth Clavioline he made for Jörgensen, the Tuttivox (with involvement/Patents to Rene Seybold). When one crossed my way, I could not resist. But when it arrived, I was in for a bad surprise."

"WORKING CONDITION: Good- All buttons, switches and sliders are intact and working well. All presets change and idnvidual volume controls for each instrument work and sound great. There are two small issues, though--- There is a low-frequency, low-level audio "hum" that is emitted regardless of the slider volume. Then there is a 16th note high frequency "tippy tap" sound that is a constant also, which changes speed in accord with the tempo slider. Almost like a click track going softly in the background. Neither of these sounds are off-putting in tone, and they are largely outdone by the pleasing sound of the drum tones. We suspect a re-capping of the power supply or some other simple service would handle these issues. It would be worth it, because this thing sounds great!"
