The TurboHarp / ELX is a Richter (aka diatonic) harp that incorporates twenty individual pickups - one for each reed.

While the full capabilities and musical possibilities have yet to be explored, some advantages of the ELX are:

• Allows you to patch different effects on bass and treble octaves of harp, such as: 
• delay / reverb on low end and distortion on high end, or 
• chorus on low end and flanger on high end.
• Enables you to distribute different notes to different channels, creating stereo or 3-D mixing effects.
• Allows you to individually balance levels of each reed or contour levels from low to high end.
• Avoids feedback by eliminating acoustical coupling between speaker and pickup.

The "Overblow Harp"  was designed by cardiac surgeon, Dr. Henry Bahnson in 1990. The aim was to make the "missing notes" available for the average player on the diatonic harmonica-- that Howard Levy was hitting with great facility. He knew other notes were available on the ten-holer but the same tones were available by normal playing.

The first overblow harmonica was hand-filed and the first batch of one hundred cost over $120 each to make. They have all been either sold or given away, and are currently very rare to find in circulation.
