there are hundreds of pro horns out there, not just the strad! and then there are hundreds of variations on them!
just because everyone plays a strad doesnt meen they are the best, nor will you like it, everyones different
the main difference I found over my old intermediate Bach Omega and my new Selmer Concept TT- which is a pro horn is apart from the build quality is the sound quality!
with my omega when I played lead I would overblow very easily with my TT that wont happen, ever because of the larger leadpipe
now the best thing Ive found with my TT is the range of colours I can create, I can blend into an orchestra, brass quartet wind band, but also blast out on lead, can go from mellow to bright in a second, I love it!
on my hunt for my TT I tried around 15 different trumpets ranging from £500 to £3000
if you want a pro horn you need to go and play some and see, hear and feel the difference!
go down and try them out and pick which one you like the best
