VIOLECTRA- THE TRUE PIEZO-ELECTRIC VIOLIN
success lies in its combination of an innovative instrument design with
a unique system of piezo- electric bridge transducer technology.
literally means 'pressure sensing').
This works by replacing the acoustic
body with a skeletal- frame body construction. The piezo-electric signal
produced is directly sensing wood
vibrations with no possible loss of
tone production, distortion or feedback usually found when amplifying
through an air born acoustic body.
Violectra works by the string tension
over the bridge being increased in mass by the wooden frame underneath.
This is similar to how a tuning fork
increases in volume when struck and
placed upon a wooden surface. An active response is created by the interaction
with the arched and open
frame of the body underneath. The result is a powerful
output with a balanced and full tone and the dynamic response more accustomed to an

Over the past 10
years, we have developed our own ideas and production
techniques with piezo bridge making.
All Violectra bridges are custom made to our

The early Violectras used Barbera Transducer Systems from New York
From 1995-2008, we used a bridge system developed for
Violectra instruments in
collaboration with a leading manufacturer
of piezo transducer bridges; Alun
Jones, of Ashworth Electronics, Cornwall.
Each bridge was made and
fitted at Violectra, with the transducers fitted at

Sadly, in June 2008, Alun died suddenly while out rowing a boat. His
work of over 30 years in transducer technology was innovative and unique
and was used extensively used in the trade for amplification of all stringed
instruments, acoustic and electric.
Also a brilliant guitarist and musician,
Alun is greatly missed.
