Probably should know this, but I don’t. I just noticed a horn for sale with a “pitch finder” / trigger on the tuning slide. It just occurred to me, how exactly does it work? Meaning, do you have to told pressure on the trigger constantly to keep the slide in the approximate right place until you move it for pitch adjustments? Obviously a first slide trigger holds the first slide closed until you extend it, but how does that work when a trigger is on the tuning slide?

I don't know how the one you saw for sale works without seeing a picture, but the one depicted on Charlie Melk's website "Services" page under "Custom Work" (http://charliesbrassworks.com/services.php) shows knurled nuts on each threaded end of the 'throw rod' between the trigger assembly and the slide brace. I am guessing that one could adjust the effective length of the throw rod so that the slide is set at a predetermined tuning position, and the trigger squeezed to move it outward from there.
I suppose you could also use a finger ring trigger without any spring action in the mechanism. |

I had a LeBlanc C trumpet that had an adjustable 1st slide trigger. It had a stop screw that would hold the slide out to whatever length you chose.
Most of the tuning slide triggers I've seen in this area on legit player's horns are totally adjustable, in and out. Amazing what's become almost a requirement in that world. _________________ "Strive for tone." -John Coppola

Pitchfinders are triggers that move the main slide.
Sometimes spring loaded, sometimes they only move out, not in. If it just moves out, it’s for bringing down sharp notes.
For the system to work, the main slide has to move really easy. Horns generally play better when the main slide is really tight.
I put one on a horn to get the upper G down, and it was ok, but the whole horn was better before the alignment and easing of the slide _________________ Mouthpiece Maker

Ok….makes sense now; adjustment screws or nuts would hold it in a pre-designated spot. Guess I should have figured that out. 🤦🏻
