Thank you for your interest in the TurboHarp/ELX. We are also quite excited about this project, having now worked on if for over 10 years. The harp is comprised on a standard Hohner Special-20 equipped with a pair of "electric" TurboLids. Within each of the TurboLids are ten optical pickups that sense the motion of each of the reeds. The output is then conditioned through a small mixer that provides line-out signal for either recording, broadcasting, amplifying, etc.
In addition to the mixing abilities that this harp enables, the most important benefit is the ability to add electronic effects using your favorite effects unit: delay, fuzz, flange, chorus etc.
We envision two models. An "economy" version will provide a single output, while the "Deluxe" version will provide four channels: low blow, low draw, high blow, high draw. The latter will enable some very interesting stereo effects.
The current status of this project is that we have completed a fully functional prototype. We are currently seeking additional investment to begin mass production.
Thanks again for your interest in the ELX. Stay Tuned for more!
