My band director bought this bass bone brand new for our jazz band, and I’m in love with it. It is really good quality, can really bring out low notes and a blast to play on. Pricy, but very well worth it in my opinion
Slightly used instrument purchased about 3 months ago. Seems to suit me well (I'm switching from tenor in my 50s), and sounds very good. Some issues, possibly common to all double trigger trombones:
- I need my Rath hand rest - I'm fairly slim and don't have strong hands, so without it, manipulating two triggers and supporting the weight is very difficult.
- The design favours the first (F) trigger in various ways - straighter piping, and easier operation with the thumb paddle.
- The second finger paddle for the second valve (G flat of course, not G) takes a bit of getting used to. Both sets of valve piping have long slides, with the overall effect that if you want E and C in first instead of F and D, it's possible.Only practical use I've found so far is that the E-pull makes a G bass gliss in "The Clowns" playable.
- The case is well-made, but mighty heavy. It's bigger than it needs to be - you could certainly get a 10.5 inch bell in there, though possibly with different padding. The compartment for 2 mouthpieces is big enough to take enough other gear for most people.
The key to any purchase, though, is trying as many instruments as you can. I didn't expect to buy this one, but it played the best of the 7 basses I tried when buying. The basic design is very old - model 50s apparently began in 1938, and I've seen a 50B promotional photo that looks 1940s at the latest. But Conn-Selmer seem to have made the 50B their main bass trombone model, in the same way as the Conn 88H is their main wide bore tenor - no other bass in their range has as many variants. This model (like the single valve closed wrap 50B) seems to be more easily available than the ones with newer valves.
