Recently, a 12 year old student of Dr. Krentz’s performed St. Saens Concerto with the Seattle Symphony. The first thing the cellists of the section said to him was:
What cello is that? It sounds great! It’s so powerful!


The bass bar in a a string instrument is an essential link in the transmission of string vibrations to the top of the instrument. Vibrations travel through the bridge and into the top and the bass bar, centered under the bass foot of the bridge. Each time the bridge rocks back and forth, the bass bar also moves up and down. By lowering the mass of the bass bar by 50% while retaining its other factors, the Krentz bass bar is much more efficient. Energy transmitted to the bass bar is not eaten up by moving unnecessary mass.

Sports cars have more horsepower per pound of car to move than conventional cars. That is what makes them fast and handle so well. By lowering the amount of mass that must be moved before the instrument speaks, K. Michael Krentz instruments are faster and handle better than conventional instruments. This translates to making your music more dynamic. Leaving you inspired by your instrument to push the limits.



Krentz String Works began ten years ago as a conversation between respected cellist, Dr. Kevin Krentz, and well-known luthier, Robert Brewer Young. Kevin needed a great modern cello from a master maker with a balanced approach to all the facets of fine instruments, and Robert needed a fine cellist with wide experience and a talent for turning adjectives into practical feedback on his already celebrated modern instruments. Thus began a beautiful and industrious friendship.

Kevin, who had already invented his magnetic-field method of driving the strings of instruments to play them in, challenged Robert to push the cello further by both interpreting current research together as well as collaborating on their own. Robert continues to create outstanding cellos that are in the hands of professional players all over the world. Kevin continues work that ranges from how cellos function to cello technique with a focus on practical experimentation and testing. While inventing unique and powerful tools to address the needs of makers and working musicians.

We welcome the opportunity to show you an instrument at our location in Seattle. An instrument’s tone can be adjusted very easily and it is important that we are on hand in most cases to adjust the cello to your vision. This is impossible to do from afar and many players lack the knowledge of what can and cannot be changed about a sound. If you are looking for a different sound than the cellos we have on hand at any one time, we can often create something new for you.

Trial Policy

Trial period is 10 days.

If the instrument is shipped to you at our expense, you will be responsible for return shipment if you do not purchase it.
