Thierry Frenkels ESPE01 module adds range and improved linearity to the Etherwave Standard and PLUS theremins. It also enhances the timbre, giving it a more brilliant sound. The EPVM1345 module for the Etherwave PRO theremin greatly improves the dynamic response of the volume antenna.
Detailed installation and tuning instructions will be provided. If you want help with the installation, you can either ship your theremin to us, or come to one of the Theremin Academies.
