EA Device model PA-01 "Theremine Wave 1" A Theremin by EA Device, which used to make original effectors and such like a garage kit. Serial number 3. Comes with an adapter. Tested and working. There are scratches and dents on the main body, but there were no problems with the sound. The antenna part can be rotated and removed. How about it as a trick weapon for dub or DJs? It's very light and compact.
