Thorwald is currently playing a custom made Theremin This instrument was built by Theremin genius Thierry Frenkel, into a wooden cabinet designed and built by Michel Chazot.

This instrument has a number of interesting features:

• The technique is hybrid (tube / transistor)
• Two speakers on the side, left and right, to be used as a stage monitor for the conductor and/or the pianist.
• Output for my external diamond speaker
• LINE OUT output, to connect the instrument to external PA's in large concert halls
• Sordino mode: this provides a 'muted' sound quality that allows you to play very softly in a very easy way.
• Special mode with classical Theremin sound
• Mute switch
• On/Off indicator
• Two open slots in top of cabinet for air circulation
• Pitch field of over 7 octaves, with extremely linear spacing
• Both antennas are fixed by a jack-like system
• Volume loop with a staccato (right) and legato (left) function in one
• Removable legs for easy transportation
