- The electronics are basic but success does not come easy, health has retired me so you are mostly on your own -

Beyond circuitry the beautiful theremin voice is alive and comes through a finely tuned window, not everyone will figure it out.

The Classic Old School Sound, not a simple whistle or nasal sound.

Build the Phoenix/Etherwave Standard Voice Mod

* It is easier to adapt to the EWS than re-invent the wheel *

.

For a free PCB "send me a picture" of your soldering & build skills after adding the 1/8" TRS Doggle

This is all too important.

* This is Not a Beginner Electronic Project *

Only you know your skill level. You will be mostly on your own. This webpage is to show you what I have learned over my 20 year theremin journey. I am not here to be your teacher and you build at your own risk. If you follow my directions perfectly and do not substitute anything you will have built the finest theremin ever conceived in response and sound. With an open mind you just might discover something new. The theremin is a never ending journey.

* I will not be able to help most troubleshoot *
I have a date with destiny
