Yet Another Etherwave Standard Bass Mod
Originally posted by member dewster, this forum thread details another mod you can make to your Etherwave theremin to improve bass range performance and timbre.
EVPM1345 Etherwave Pro Volume Modification
This module improves the volume response of the Etherwave Pro. Original Etherwave Pro theremins have what is called a snappy response. The softest audible sound is already quite loud, as silence is followed by a jump in volume from zero to a starting level of about -40dB. The consequences are not only a reduced dynamic range but also the impracticality of sophisticated expression at very low volume.
ESPE01 Etherwave Standard Pitch Extension
This module adds about 2 octaves of range in the bass register, making the Etherwave theremin sound even lower than a double bass. The linearity improves considerably over the full pitch range.
PAiA Theremax Mods
Fred Nachbaur has written an excellent article describing his modifications to the PAiA Theremax. The article lists some improvements to the overall playability of the Theremax.
