Re: SD SJB-5 18mm bridge?
Welcome to the forum.
18mm bridge saddle spacing equals an overall span of approximately 72mm.
SJB-5 has a blade polepiece, permitting a string sensing "window" of up to 73.6mm for each position.
Provided that the fingerboard and bar polepieces are of similar radii, all of your strings will be sensed correctly.
