A few months ago, I got an Olds flugabone/marching trombone and posted about my experience with it. A few days ago, my trombone fanatic brother-in-law

bought me a used Yamaha YSL354 (for the irresistible price of $125). It’s in really decent condition. I didn’t know what to look for (and maybe still don’t), but after closer inspection at home, it seems that the slide doesn’t belong to the the bell. They fit, and the bone sounds fine (no air escape that I can tell), but the lock nut hook doesn’t reach the lock. By a couple inches. And the slide says DZ instead of Yamaha on it. Maybe that’s what the slide is supposed to say, but I don’t know and that’s why, in part, I’m posting to find out. But for sure, it doesn’t belong because the lock is way too far away from the lock nut hook. I think a repair tech can move it and place it so that it works. Will check on that soon. Otherwise, I just have to be really, really careful to not let the slide drop.
I noticed that my slide trombone seems easier to play than my flugabone. I also noticed that the flugabone has a warmer/darker sound and the slide bone is brighter and seems louder than the flugabone. Pedal tones are easier for me on the flugabone than on the slide bone. I got an app on my iPad that shows the slide positions (very handy), and I’m getting the idea of how that’s supposed to work.
Anyway, seems to me like the slide trombone and the flugabone are very different animals. I like them both, but each gives me a different vibe. Any thoughts? Thanks.
