I've had mine a couple of weeks and the more I play it the more I like it. I'm using a king 5G mouthpiece and as a long time tuba player, it's like playing into a thimble. I find myself yearning for more mouthpiece...
How large do you think can I go?
I've considered trying a 4G but I'm not sure a 4Gs are alike.... I looked hard at one and was almost ready to pull the trigger when I hit on some comments that it was different than the usual version.
