im my personal opinion, buy a used instrument ... and besides, you can find amazing deals on used professional instruments.
When it comes to saxophones, I moderately disagree with this, unless you do a very, very focused search. For the sake of argument, I did this, recently, not only because I wanted to see if it could be done, but because I got some great pictures out of it. The article:
"... And They're All Around $1000."
I disagree a lot more with this on other instruments. For instance, there are
a lot more clarinet makes and models out there than there are for saxophones. Again, if you have someone to give you targeted advice about older instruments, the problem goes away. Fortunately or not, I've never seen any article on this for any instrument and for any user other than "student." It might be a good idea to start some articles on this.
And second, a used instrument has already been played by multiple musicians so the said instrument has already developed its sound and timbre
I think it's pretty hard to argue that this happens with woodwinds. First, there are multiple entries on this website about "blowing out" wooden instruments, an argument which implies that older wooden instruments aren't a good idea. Second, while you can
prove, for instance, that lacquer does change color with age/care or lack thereof, the metal itself is stable. I think that all of this really boils down to condition and how the instrument is set up.
with brand spanking new instruments you can only play for a certain period of time before you have to stop playing.
When your gums start bleeding, you've played for too long. Otherwise, I don't really know where you're going with this comment.
