Genuine Bach Stradivarius Strad Trumpet Valve Piston Spring - Set of 3 Springs

I put these into a first generation bach mercedes from about 1982 and they worked fine. Those were essentially a strad with a 2 piece bell at the time. The old springs went into a blessing L-1. They were 1/8" longer than stock so those valves are livelier than they were as well. win-win.

This works for Allora AAFG-103F, very smooth springs, they are obviously for trumpet but they work amazing in Flugelhorns with springs under valve too, stock springs are very stiff in comparison so it is a good upgrade. They are not exactly the same measure but they work very well.

Fingers felt like they were flying over notes after changing springs

Works Great! They fit my Cecilio trumpet.

Bach Stradivarius Strad Trumpet Valve Piston Spring are the best I've tried and I have tried several off brands very happy with them however Harmony Music shipping really sucks!!!!!!!!!!!!

While cleaning my springs, I let them soak in a bowl w Dawn dish soap to remove the oil. Bad Idea, that's why I needed replacements, as they got tangled up...........

These springs worked beautifully in a restored Bach 72 Strad Lightweight. The feel of the horn is much crisper now since I replaced the springs. This horn is a daily player that performs classical, jazz and church music.

These worked great. I have a 1974 trumpet that needed an overhaul, these springs put new life into the valves and their function

No sé si sean los originales de la marca pero funcionan de maravilla!!!
