Moog Etherwave Theremin Black Purchased new in 2003, used only at home. Due to a busy schedule and the instrument's difficulty, my enthusiasm waned within six months, and it was stored in a cardboard box at home ever since. I tested it recently for this listing, and there were no operational issues. The contents include the main unit, antennas, power adapter, instruction manuals, and two instructional videos that came with the purchase. Contents Details: (1) Theremin Main Unit ・I believe it's in relatively good condition, but there is a dent on the top panel (see the last photo, possibly the original wood condition?), along with minor scratches on the top panel that don't show up in photos, and white scratches (or stains?) on the left side (near the left-hand antenna connection). ・The felt pads on the bottom feet are slightly misaligned. (2) Pitch Antenna ・Slight discoloration due to aging. (3) Volume Antenna ・Slight discoloration due to aging. (4) Dedicated AC Adapter ・Slight discoloration on the metal parts due to aging. ・The power plug is a 3-pin type, so I will also include a 2-pin adapter that I have on hand. (5) Warranty (Expired) (6) Japanese Instruction Manual (7) English Instruction Manual ・Includes circuit diagrams, etc. ・Some corner folds. (8) Clara Rockmore / The Greatest Theremin Virtuosa (VHS) ・Audio: English (no Japanese subtitles) ・Features performances and playing techniques by theremin player Clara Rockmore. ・Occasional noise, but it played without problems. (9) MASTERING the Theremin (VHS) ・Audio: English (no Japanese subtitles) ・Instructional video by Lydia Kavina, a relative and disciple of Leon Theremin, the inventor of the theremin. ・Occasional noise, but it played without problems. Please check the photos for the condition. If you are concerned about minor details or are looking for a perfect condition, please refrain from purchasing. Thank you for your consideration. ******************* The following are for search purposes: Etherwave Theremin Etherwave Theremin Big Briar, Inc Big Briar Moog Music Moog Music Moog Bob Moog Bob Moog Robert Moog Robert Moog Lydia Kavina
