I was going back through some old posts and found a short discussion of hole diameter in trumpet mouthpieces. One member noted that they, "prefer 5/64" and 3/32" hole size in [their] mouth pieces...[and] sometimes bore the mouth pieces 7/64" to get more of a jake or gobbler yelp sound." I was curious to hear what others think about hole diameter. What widths are you using on your calls?
