Well my playing background stems from the Salvation Army so most of my playing is Brass Band Arrangements. But I also upon occasion play in a small ensemble of Bass Guitar, Piano and a small horn section.
The horns I play are:
Cornet:
(Currently) Boosey and Hawkes Sovereign Bb (Large Bore)
(Previously) Besson Sovereign (Large Bore)
Trumpets:
Yamaha Custom C (It has 2 bells, one is brighter sounding than the other)
Yamaha Custom D/Eb
Flugel:
Yamaha Flugel
And occasionally I get to play a Kanstal Custom Class (I really like this horn)
Mouthpeices:
Cornet: Sparx 3 (

Trumpet: Bach 3c while I wait for my GR/Sparx custom trumpet mouthpeice to be made.)
Flugel: Bach 3b / Bach 1b
Any cornet players out there should check out the sparx mouthpeice line I am really happy with my Sparx 3.
