Received my Piggy CC today and it plays great, with the right mouthpiece. My PT-86, which has a slightly smaller than European shank, plays great on this horn, as does my PT-50s. It appears that the horn had the paddles changed out. The first 3 paddles appear to be the same and the 4th is thinner and has a different design.
Played lots of long tones to find the tuning, played some etudes, and worked with my son on his Euphonium Solo for UIL Solo and Ensemble.
I am looking to forward to playing the piggy at a rehearsal tomorrow night.
Here it is next to my 5/4 B&S CC.
