The Etherwave Standard Pitch Extention module greatly enhances the timbre and linearity of the Etherwave Standard and Etherwave PLUS theremins. The pitch field will be extended with up to two octaves in the bass register, while the high register remains unaffected. A detailed explanation of the module can be found here.
A detailed installation manual is provided with the module, along with two capacitors that can replace the capacitors the module connects to on the Etherwave circuitboard.
Disclaimer: the module may work less efficient with older Etherwave theremins, sold under the Big Briar brand. Installation on those theremins may differ from the steps of the manual. If you have one of the earlier Etherwaves, we can give you the information required for a succesfull installation.
The module is shipped without tracking, in a bubblewrap envelope. The normal shipping costs are 2,90 Euro. Registered shipping is possible at an additional price of 15,- Euro.
