Funny thing. As subjective as is can get with mouthpieces. I always feel beechlers are much more resistent than the ponzol custom I have.
The new ponzol custom I have is a high baffle typ. Soundwise very close to a lamberson sb7. Good for funk & soul but also can play soft. Not as full on the low side as the lambo. But also very easy playing. I´m preparing some soundfiles with all of my bari mpcs for comparison soon.
