My new horn will shipping very soon and since it's been about 30 years since my last new one I have a few questions that I hope you guy's can help out with. 1. How long did it take you to trust your new one and were confident in using it as your primary? 2. I plan to sit down with a stobe after having played it awhile to zero the tuning. Beside that are there any specifics you have run across that were issues for you? 3. Were there any special maintenance points that I should really pay particular attention to? 4. How long did you have it before you let anyone else play test it? Thanks in advance for you insght and help.
