This theremin has incredible range! The range on this theremin respects what I call the "arm length" rule. Most set up their theremin for a playable range of about 2.5 feet. Watch out for others selling theremins where playing requirements mandate putting your hand within a couple of inches of the antenna. Ease of play is the key to my theremins. This theremin features a pitch control knob so pitch can be set to go up OR down as you move your hand toward the antenna. By adjusting this knob, you can set starting pitch and sensitivity. The Great Sounding Theremin at a Great Price also sports a quarter inch jack so you can connect it to your amp. As with most theremins, this instrument requires an amplifier to be heard. This theremin has true theremin sound - not a poor sounding square wave like some other theremins - and a strong signal that will drive your amp well. BONUS - This theremin includes at NO CHARGE a U.S. standard plug in power supply so you never have to worry about batteries. Value priced, this single antenna theremin is ready for your next gig!
