The Krentz Modulator changes, rather than absorbing vibrations from the top of the cello. As a result, there is no depreciation in sound quality. Rather, the device actually increases the efficiency of the instrument, allowing the musician to subtly control important aspects of the instrument’s tone.
Designed to fit an f-hole with the following size:
Violin 8.3mm | Viola 9mm | Cello 14.1mm| Bass 22mm
