Vintage Hammond Solovox

via this auction
"1940s Hammond Solovox with tone cabinet in working condtion. This was made in the 40s or 50s. It was made to accompany a piano. It would attatch to the piano and has a knee control, it was one of the first Synthasizer ever made. It is a model L series A (cabinet also)Its kinda odd looking thing and it actually works, it takes a while to warm up and a few keys you have to push down harder than others. When I bought it one of the buttons was broken, I bought another keyboard model j and replaced the broken button, so whoever buys this will get the 2nd keyboard for parts. On the front of the instrument below the keyboard there were a series of large thumb operated buttons for oscillator range (switch-able +/- 3 octaves: 'soprano', 'contralto','tenor' , 'bass'), vibrato, attack time, 'deep tone', 'full tone', '1st voice', 2nd voice', 'brilliant' and a switch for selecting woodwind, string sound or mute. The Solovox was able to create a range of string, woodwind and organ type sounds."
