Factory made in Southern California, the 7440 Hybrid is a 4 string fixed bass bridge that combines simplicity of design with full adjustability. Height, intonation, and string spacing adjustment allow bassists to set instruments up to their exact specifications. You can easily achieve a very tight 14mm and up string spacing. Kahler fixed bass bridges feature quick, easy string-up and awesome sustain. To accomplish this, they use a steel adjustable mounting plate designed with an intonating angle, and 3/8x40 pitch steel saddle witness points. A bassists ultimate fantasy bridge!
