I just picked one up this weekend, does it ever stop rolling? When tuning, it will stop for a quick second and kinda roll back and forth really slow. I know the guitar is in tune and the best it seems the Peterson will read is just barely pausing after it slows down, is this normal? I think it's kinda hard to set intonenation like this with it not really stopping. I upgraded from a Korg GA-30 and the SS2 said the Korg was flat. Also, to tune down a 1/2 step according to the instructions, I would just use the b1 setting? Sorry if this has been discussed before, I looked through a few pages that came up in the search and didn't find the answer.
