I picked up an excellent shape Getzen Super Deluxe Tone Balanced Cornet today. The only thing that needs attention is the bell - it is a bit crumpled. I have read in some of the other posts that this must be a common thing with these horns - what is that about? Take a look at the pictures and let me know what you think it needs. Do i take it to the local repair shop, or need a big time repair shop. Is it reparable? Thanks for the guidance.
