Sometimes you need to change things up a bit. I have been playing the same Selmer Mk VI since I was in high school! We have been through a LOT of gigs together.
But recently I bought an old Conn Chu Berry and have been having a blast (literally) playing it. It’s nice to play since it feels so different from my Mk VI.
I highly recommend changing on occasion just to re-discover and re-appreciate what you already have!
