The current mouthpiece, you mean? It might well be junk, but it's difficult to tell, although actual players of saxophone have not commented on it so far. The comments to date are that it's a "decent horn" and a "good blow" rather than specific to the mouthpiece... I find some days I get a reasonable sound, and some days are not good, and some days are both good and bad - so at the moment, I think it's likely to be me! (The new reeds do make it sound better, though that could be my imagination)You might be wasting your time. May be Ok, may be junk, and if it is tonal consistency is likely to be very elusive.
