Long time-lurker, first-time poster. I've been 'bone playing for 30+ years with a few breaks just in school bands/orchestras and then community brass bands in Australia. Playing a Bach 42B with Yamaha 51L mpce.
With the inspiration of an experienced 1st trombonist joining the band I'm trying to level up a bit in my playing, practice more and pay more attention to where I'm dropping the ball.
I've noticed that moving from F to G on the stave (i.e. 1st to 4th)




I've been trying some things like Caruso's 6 notes as warm ups but thought I'd reach out to the Brains Trust here for advice.
Additionally, there's a bloke nearby selling a Packer JP3320 Rath - is it a dumb idea to try it out and see if it blows better than my 42?
Thanks all.
