Seems like there's a lucrative Starfire bass saddle business waiting to happen. Rosewood, Maple, Ebony, bone, brass, graphite, aluminum and more.
I see a few basses out there with really goofed up saddles. Like the one that was a Lefty then back to normal with all the extra strap button holes, the saddles on it are pretty chewed up.
I felt so fortunate to get an original saddle from Ray Bowen60, it was a touch darker than mine so I removed and very lightly oiled mine to match, a fantastic match. I wouldn't expect a new saddle to be a great match to the old Rosewood. I'd have to say it's probably Brazilian, it's very nice.
The reason the saddle was gone I theorize is that it got broken from an impact that bent the slider past 90º towards the adjusting screw. It was somewhat visibly bent down and the only way I could get the new saddle to sit flat on the bridge like the others was to take a 10" crescent wrench with appropriately wide jaws and bend the slider back to straight, carefully. You have to go past straight a touch because the steel is springy. Great steel, did it with ease.
I'm very impressed with this bridge design. The ease of adjusting intonation is unmatched by anything else I know of. I like the old timey pan head screws. Undo screw, lift slightly loosened string, slide saddle, tighten screw, done. Also the ease of centering the strings, moving all strings from side to side at the same time is unmatched.
If only they made this bridge for guitar.
