Krentz Modulator

The Krentz Modulator is a precision‑engineered accessory designed to help string players manage troublesome wolf tones and refine the tonal response of their violin, viola, cello, or bass. Unlike traditional wolf eliminators that simply absorb vibrations, this innovative device modifies the instrument’s vibrational behavior, which can reduce or smooth out harsh resonances without degrading overall sound quality.

Crafted to fit through the f‑hole, the modulator is positioned inside the instrument where it interacts magnetically with a corresponding external magnet. This setup allows players to experiment with placement and tonal adjustment, giving you control over how your instrument responds in performance or recording situations.

Designed to fit an f-hole with the following size:

Violin 8.3mm | Viola 9mm | Cello 14.1mm | Bass 22mm

The Krentz Modulator offers a refined approach to managing challenging tonal behavior while preserving the natural characteristics of your instrument.
