3rd valve slide on my Yamaha YTR2320? Hey! I recently got a Yamaha YTR2320 for like $150, and it's in really good condition. I have a few questions though! - The 3rd valve slide is not really working very well. It's not very bouncy backwards as I've felt with expensive trumpets, it kinda just goes out to where I pull it and stays there, and also it's quite slow and not so smooth (tried different lubes, not sure which one I should be using?) Any help on this? I did clean it out all together with soap and warm water, rinsed it with sponge that comes with trumpet cleaner kit. I want a nice springy and very smooth 3rd valve slide... - The finger rest for the pinky of the right hand is missing, what's the best way to accommodate for this? Thanks! W.
