This little device REVOLUTIONIZES my violin. Seriously. I’m probably going to practice all night. Kevin Krentz is a freaking genius. I’m seriously impressed.

Emma McGrath, Associate Chair of the Seattle Symphony Orchestra

It works beautifully. I have tried all the solutions out there and nothing has ever worked. The Krentz Modulator not only works but improves the tone in general because it seems also to eliminate imperfections in the strings themselves!

WHAT IS A WOLF NOTE AND HOW DOES IT HAPPEN?

As you remember from physics class, when 2 vibrations match, they double in power, volume.

When 2 vibrations are exactly opposite they cancel each other. Silence. This is how noise canceling headphones work.

2 vibrations on the cello mixing!
#1 the volume of air inside the cello doesn’t
change and vibrates strongly at the
frequency of your wolf note.
#2 when you play the same note,
the top of the cello vibrates.
On the cello the 2 vibrations
almost match.
Sometimes the waves are the same
and double in volume.
Sometimes the waves are opposite
and cancel each other.

The Krentz Modulator has saved my relationship with my cello. Not only does it solve the wolf issues but it to also enhances the instrument in ways I previously did not experience before. This is by far the best product out there.

Patrick Jee, New York Philharmonic

HOW IS THE KRENTZ MODULATOR DIFFERENT?

The top of the instrument vibrates in different
places for different notes. It is most active here
in the wolf register of the cello. Imagine this
excited vibrating area like a trampoline.
Rather than simply putting something
in the center of the trampoline to stop it,
the Krentz Modulator operates
at the springs on the side. This changes
the vibration instead of simply absorbing them.
