I have spent the last year or so playing on an ageing Yamaha YBL321 Bb/F bass trombone and I love it. However the slide isn't very good and I really miss the versatility of having the second plug. What I would really like to know is people's experiences ie what they know about the cheaper chinese made instruments, not what they have heard. I'm on about John Packer, Wessex, Coppergate, Peter Gane, Catalinet etc. I am not going to spend mega bucks on a trombone that I have no real need of and I am the first one to accept that it is probably better to spend on a good second hand instrument than on a new copy one. The only preference I have is that it must be independent.
