I have to say here that anything 5 cents or more in my book is =
considered a pitch raise, especially when it comes to smaller verticals =

like you do a normal tuning. Then turn off the machine, and do a normal =
tuning. On the pitch rise, you don't have to get picky with the unison. =

take to do the tuning.=20
