I have known forever that brass mouthpieces have a lot of energy loss. Because of that I wanted to try out steel mouthpieces. I got a full set of the David Hickman line of mouthpieces. I played them for a little while and I loved the rim. It is so comfortable to play. I love the increase in dynamic range on both ends. They have some nice softs.
The problem was that I have played 22 throats for 35 years and these were not that large. I sent an email asking if they would enlarge the throats (I didn't want to mess with steel mouthpieces.) They said send them back and they would enlarge the throats the day they got them. I then asked how much money to send with the set of 4. I was told to send 20 and they would have a burger and beer on me. (Ivan Giddings was very nice about doing this for me.)
I am not impressed often by a business. I am impressed by the customer service and the excellence of craftsmanship that I have seen with the GW mouthpieces.
BTW I love the way my Hickman pieces play. Give steel a chance. They play really well.
