About the THEREMANIACS Theremin This is a genuine radio frequency heterodyne analog Theremin. The operating principal and the output are extremely faithful to the original Theremin at an affordable price. Sound is not compromised by using IC chips or optical style circuits that are actually audio oscillators and not true Theremins. Theremaniacs Theremins incorporate high quality polystyrene NPO and silver mica capacitors for stability and drift free operation. These frequency determining components are also embedded in silicone to prevent drift. Theremin is also frequency agile. If interference is heard such as radio, TV or computers, you can adjust the operating frequency away from the noise (plastic tuning tool included).Output is 5 octaves. Playing range covers greater than 3 octaves. A three way 1/4 inch phone jack turns the Theremin on when a guitar cord is inserted. Plug it into an amplifier and it will sit quietly until your hand is up to four feet away where it will emit a low growl. This sound will increase as your hand comes nearer to the antenna until the pitch is so high it is inaudible. The Theremin has an external sensitivity control and coil adjustment. The sensitivity control (on the outside) determines how close your hand has to be before the theremin starts to make a sound. Antenna is collapsible for transport. Theremaniacs Theremins have the ability to change the timbre of the output sound from a mellow sine wave to a coarse sawtooth wave by relocating one wire. It is powered by a quality 9 volt battery that lasts a very long time (about 500 hours of continuous use) and is easy to replace. There is no drift as battery power is consumed during use. Draws only 1 milliamp, far less than ordinary effects pedal. No need for an adapter, power strip, surge protector - no searching for an outlet. Set it up anywhere you want! Quality Alkaline battery is included. Only pure DC battery power offers hum and noise free operation with circuit stability. Tested for FCC compliance. My product line includes a 'black box' theremin as well as a no-solder theremin kit. The finished black box, antenna style theremin is plug and play - ready to go. Microphone stand style or rubber foot table top model is $139.95 each plus shipping ( $15.00 ). The mic stand mount has metal threads and this is a solid attachment to the main housing by metal fasteners and plastic welding solvent. Sorry, microphone stand is not included. Your theremin can be made with rubber feet instead of a mic stand mount for no extra charge! The circuit board solderless 'Kit' is available for $99.95. Shipping $15. This 'kit' version includes the assembled circuit board, antenna, tuning tool, sensitivity control and knob, battery holder, and instruction sheet. You would need to provide the enclosure. Most people associate the sound of a theremin with vintage science fiction / horror movies. A wiggling motion of the hand produces a vibrato effect. Input to a reverb, echo unit, flanger, or others will create wild effects! Run this through an effects rack and you will be amazed at your sonic creations! Check out the Harmonic Percolator!
