Helpinstill is an
US-based company which produces a unique
electromagnetic pickup system for amplifying grand and upright
pianos on stage. During the late 1970s the company also marketed a range of portable pianos ready-fitted with the pickups; these instruments were built by
Kimball to Helpinstill's specifications. The company's founder and namesake, Charles Helpinstill, performs in Houston with his band,
Ezra Charles and The Texas Blues Band.
