Upgrade Kit Theremin Plus

To transform Theremin Etherwave into Plus

You can order it one of two ways. The Factory Upgrade let’s Moog do the work and we’ll check your Etherwave as well. Or you can choose the Field Upgrade above and do it yourself. Either way, the result will be your Etherwave with the addition of all the great ‘plus’ features: Pitch Preview, Headphone volume knob, separate headphone or pitch preview output, on/off switch with LED indicator, two Control Voltage outputs and one gate output.

If you choose the Field Upgrade, simply select “Field” from the drop down menu and click on the add to cart button above and the following will be shipped to you. The Etherwave Plus printed circuit board, a new front panel, headphone volume pot, headphone volume knob, headphone jack, on/off switch, LED indicator, and a template for drilling the bottom of your Etherwave Standard. Once received instructions for installing the components and soldering (7 solder joints) the board will be included. Have fun and good luck!

Note: Please review the Field Upgrade Manual before ordering to make sure you’re comfortable performing all of the steps necessary.
