rim of cup is very comfortable and greatly helps my endurance. backbore is free blowing and dose'nt offer as much resistance as some of the mouthpieces I've played on before.

Really first class!

Precision parts, top-notch - very fine craftsmanship

Pickett Brass is a 1st class organization that I recommend to ALL my trumpet friends.

peters mouthpieces are great !

Peter sent me a #1 and #2 backbore to try. I was very impressed with the quality workmanship. I am looking forward to the duplication of my vintage custom Giardinelli 10M he is making for me.

Perfect, as always!!

Perfect fit and look.

Outside of barrel style heavy trim kit looking great on my Yamaha Xeno 8335RGS, it really helped produce a more focused, powerful sound. Very Satisfied

No problems.
