I briefly played another musician's Claravox recently...never mind who or where. I continue to play my Keppinger Mark 1; a ten-vacuum tube (valve) theremin of the traditional, heterodyning type. My impressions?
1. The Claravox is a beautifully executed instrument in appearance.
2. The tonal field appeared to be quite uniform. The volume appeared very expressive and the instrument did mute completely.
3. However, the instrument did not appear to be "alive"; it felt like an imitation. I can't really put words to it. Almost a visceral reaction that is noticed immediately. A well-known theremin technician/repairman/engineer told me he knew EXACTLY what I meant and described his short summation. I won't repeat his words here.
Summary: Although the Claravox may be the ideal instrument for some (assuming its technical flaws are ever worked out by Moog), I will stick with my cantankerous, heavy, yet beautiful vacuum tube theremin.
Be well my friends.
