Electro Tone Duet Sixteen

The Duet Sixteen preset kit was manufactured by the Electro Tone Corporation in the 1960s as an after-market add-on for Hammond M-2 and M-3 spinet organs. The Duet Sixteen was not suitable for Hammond M organs, but could be fitted to M-100 series and L-100 series, even though these models already had Hammond factory presets. For Hammond M organs, Electro Tone Corporation manufactured the Electro Tone Mark II preset kit, as well as manufacturing the Electro Tone OrganMate reverb kit for any Hammond organ requiring reverb and the Electro Tone PER 200 percussion kit.

Some very good photos of the Duet Sixteen can be seen at http://avintagesound.com/ELECTROTONEVOICEPRESET.aspx.
