Most of my playing is a commercial idiom, as such I was keen to try some of the bobby shew mouthpieces. I had tried a few in a shop and decided to buy from thomann in a combined order.
The quality of the product was outstanding. The plating was flawless, like a mirror, there are no machine marks. The bore and backbore were blemish free, too.
As for sound - it is bright and definitely has plenty of core.
With mouthpieces as shallow and soft on the rim you must resist the urge to press hard and over-blow.
Personally I find that I play sharper on this piece than I do on my other equipment. I just lengthen the main slide to combat this.
