The idea of the electronic pickups came forth from
the desire to build a feedback guitar. In order to
have a strong feedback from the pickup to the
actuator, it was necessary to come up with a
different kind of pickup than the coil based pickups,
because coil based pickups will give unwanted
feedback between the pickup and the actuator,
similar as the feedback between microphone and
loudspeaker. Piëzo's did not have the sound that
was wanted, and also to create a hexaphonic
feedbacksystem a would be necessary to place a
piëzo under each string. After long experimentation
and improvement it was found that the electronic
pickups have many more possible uses than only
the feedback guitar .
