I think i will try the yamaha for a while and see if i can get on with it a bit better and if not think of a polite way of telling them.
Wise choice. People are finicky when it come to getting and giving gifts. One of the best ways to hurt someone's feelings is to put a negitive feel on a gift that's been received.
I tell my 7 year old daughter:
"Even if it's something you have or something you don't like, ALWAYS say thank you and never think its nice to give it back to the person who gave it to you"
In a nutshell you rob them of the good feeling of giving something.
Have the Yamaha cut down to make it a C trumpet. It may then have a greater chance of being played.
This will only work if you have pin striping or flames painted on the bell once the machine shop ruins your horn..
