Yamaha GP Mouthpiece Trumpet 14A4a

I have used 6 Yamaha trumpet mouthpieces in the past, however although they are high quality and good for the job they are for - 16c4 for general playing, 14b4 good for Jazz, after a few weeks using the 14A4A MP I was surprised to find it was so adaptable. The depth is shallow enough for rich lead playing but also once you get used to it, the thicker rim suits comfortable lower register playing also, and without any loss of tone or richness in timbre. I have used Curry and GR MP's in the past, but this is the one I will stick with.
