I just recieved a new trumpet, I have not played in 20 years. Iam now starting to play again and noticed that spit was comming out of the top slide of the c,g,e, slide, and not dropping down to the spit valve. Is there a jel or lube to put on the slide to keep this spit from comming out of the top slide? O r is this a bad or faulty trumpet? Plus I can feel and hear spit that will not blow out when I press the first valve.
