The KNA story begins with Vladimir Hranov, who conceived and built a prototype bridge-mount pickup for nylon-string guitar.  

As a young boy, Hranov became fascinated by radio and learned to build his own, along with remote control cars and airplanes. He began building and selling guitar pickups in the 1960s. He followed his passion to the Puldin guitar factory, where he learned to make magnetic pickups. He was quickly promoted to lead the electric guitar division.

The popular, state-run Puldin Company was eventually dissolved. Hranov continued to develop his original ideas, including a series of passive piezoelectric pickups. In 2005, he shared those ideas with Nikolay Iliev, who was the distributor of Kremona musical instruments in North America. 

The early pickups were introduced to the United States, with improved designs and packaging. The line was expanded to accommodate ukulele players, violinists, cellists, and bassists. 

In 2015, Iliev purchased the pickup company and opened a newly retooled production facility in Hranov’s hometown of Plovdiv. Vladimir Hranov remained happily active at KNA as an advisor and senior developer until his passing in 2021. We hope to carry the legacy of Vladimir Hranov and his innovative creations far into the future.
