Berkeley's Bass Trumpet

[Multi-Instrumentalist]

Right off the bat, I AM LOOKING FOR SOMEONE WHO HAS USED THIS HORN

People are always looking down on horn brands that come from certain countries, for instance everyone told me Amati was trash, and now their piccolo trumpet is one of my favorite instruments. Anyway i got off topic; I have come across BerkeleyWinds' Bass Trumpet and immediately became interested,
I dont plan to use this horn as a primary instrument at all, maybe some jazz improve if I dont wanna use my sax, so i need an instrument that will work with time to provide care between uses.
I already know the Kanstul models and other notable brands will sound better, like i said, i dont plan to use this for anything except just to play for the sake of playing (i prefer the harsher sound then that of the V-Trombones and Euphonium/Baritones)

So anyway, please only post replies if you have or have had experience with this horn, Thanks Everyone!
