you can try to oil it with slide grease or take it to instrument store.
Stuck...Seriously though - It depends on the instrument. If it really is a trumpet, then chances are it's custom made, and the mouthpiece is not designed to come off. In this case, however, it is still called a trumpet.
A slider can break if it becomes stuck, if the mechanism inside malfunctions, or if it is subjected to excessive force or pressure.
go and get it professionally removed, because if unprofessionally done you could damage the bell of the trumpet
I had this just happen to me also...we had to take the door panel off on the inside and now have to move the mechanisim manually until I can get someone to replace the latch in the back of the slider door...it's a real pain in the butt...
I use white Lithium grease (sp) lubbricante. It works great.
Yes because when a red eared slider swallows small stones they can possibly choke and the stones can get stuck inside thei turtle's system
Dizzy Gillespie played a bent trumpet, the bell stuck up at a 45 degree angle. He once had his trumpet bent by accident, the tone of the instrument changed with the new shape, he liked the new sound and subsequently had a mis-shappen trumpet specially made to duplicate the sound of the broken instrument.
To replace the screen slider on your device, you will need to carefully remove the old slider by unscrewing it or prying it off. Then, align the new slider with the track and slide it into place. Secure it with screws or clips as needed. Make sure to test the slider to ensure it moves smoothly before reassembling your device.
