Free, I ordered the one in 'C' for guitar, dealer sent this instead. replaced it with the right one let me keep this one. I donated it to our local library branch, but they discarded it when it didn't circulate for xx amount of time and my wife saw it and it wound up back with me, so offering it here. I know there are a few of you who double on a Bb instrument, so here it is for the asking. Email me at blittle48@yahoo.com
