Last month, I received an email from a German customer. The last sentence really stuck with me: "The screws have arrived-they sing."
This customer is a German artisan who handcrafts electric guitars, which he sells throughout Europe. He started out last year using our string-locking screws for the Floyd Rose system, and later expanded to bridge mounting screws, pickguard screws, and potentiometer mounting screws-replacing them all with titanium alloy.
In his email, he described one detail in particular: After switching to titanium screws, one day he accidentally plucked an open string and noticed that the sound had "become cleaner." Thinking it might be a placebo effect, he conducted a blind test-he asked one of his students to play the same guitar, alternating between steel and titanium screws, while he listened from the side. He tested six sets in total, and each time he was able to accurately identify which ones had titanium screws installed.
"The high frequencies are clearer, the sustain is longer, and the decay curve is gentler." He described the sound in engineering terms-as measurable acoustic differences.
Attached to the end of the email was a video: he played a piece on the new instrument fitted with our titanium alloy parts. With the titanium alloy components, the sound was exceptionally crisp and clear.
There are some applications engineers could never have imagined-until a screw met someone who truly understood it.
