I have just got a Yani A901 Alto Sax and it was set-up great – the supplied neck comes in and out with ease. At the same time I purchased a 92 neck and although it fits it is a little on the tight side. So I’d like to make it fit better. I was thinking using wet and dry (dry) at around 320 or 400 grit. Would this be okay? Is it the right way to do this?
