Jswers. Do they still make the Resin Model or just the HR? Altissimo is easier....Ill take 2!This is my go to piece for louder playing situations. It is made of resin, not hard rubber. It has a narrow profile more like a metal piece in mouth feel. The large baffle gives it plenty of volume but the piece is not overly bright. I find it to be in the middle, not too bright or too dark. I have also backed off and used this piece to play in situations where I do not need the volume and I still get a rich tone. The altissimo is easier on this piece than on some others I have. Overall, a great piece and could easily by the one piece you own for all situations. The only reason I do not use it all the time is that I like to try out other pieces and switch from time to time but I always come back to the Studio.
