I have a Yamaha YAS-34II Allegro Alto that I really like, but it is not quite getting the tone I am seeking. I usually use a Selmer C* or a Meyer 5 mouthpiece for playing in our Praise Band at church but the tone is a little more focused than I would like for it to be. I am looking for a bigger fatter warm (hopefully that makes sense...lol) tone than what I am currently getting. I am using the stock neck at this time and I understand that later 34IIs had the G1 neck. My hope is that a G1 or V1 neck will help me attain the tone I am seeking. I have read the later 34IIs came with the G1 neck so I am hoping it will be essentially a easy swap and the octave key mechanism will not need lengthening or adjusting. Any thoughts, experiences or ideas on either neck? Thanks!
