I should state that as Les says, the neck roller tuner work best when it is used to tuen the sax. They are a little brighter than the NY neck models. I keep my mpc 5 mm off the end of the cork next to the roller and use the roller to fine tune the sax to pitch. Intonation and sound has always been easy when using the neck rollers like this. It works as easily on the C Melody roller neck models too.
