Get A Portable Yet Rugged Theremin: The Harrison Instruments Model 302 Theremin

The Harrison Instruments Model 302 is an economy-oriented theremin featuring superb fidelity, stability and ease of use, designed with the road musician in mind. Volume manufacturing techniques have enabled the production of the 302, comparable in performance to much more expensive theremins, at an affordable price. Built to rigorous standards with the best commercial materials, the 302 Theremin is a road-ready, reliable companion for the serious musician.

Compact, lightweight at just 2 pounds, and completely portable, the 302 sets up in minutes, with battery operation eliminating the need for an external power source. Its high-impact-resistant ABS plastic case ensures durability and reliability. When used with a mic stand and a battery-portable amplifier such as the VOX DA-5 or Roland Cube, the 302 permits a theremin performance virtually anywhere. Equally suited for the studio, the 302 also provides unexcelled results for use in recordings and soundtracks. Thoroughly evaluated in the rigors of harsh travel environments, the 302 has been perfected and tested by thereminist Arthur Harrison in every-day, practical use, in both indoor and outdoor venues.

The 302's compact, symmetrical style is functional and unobtrusive, allowing a clear view of the performer. A horizontal pitch antenna permits a natural, low-stress hand position, reducing the fatigue that otherwise may result from playing traditional "pole" designs. The volume is specifically designed to increase as the hand descends toward the plate. While contrary to the traditional theremin volume response, extensive human-factor evaluation has found such a "closer for louder" design to be much more intuition-inclined and therefore easier to learn and play. While thereminists accustomed to the traditional volume method can adapt to the 302 with practice, beginning thereminists will find that the 302 method is very intuitive in nature.
