This is my third Snark, and the first with this Hertz tuning which I haven't even used. I didn't realize it was going to be as big a deal as it is. You can't just tune individual strings with the Hertz tuning. You have to tune them all each time, in sequence.
I'm not crazy about the larger bars on this model, and it doesn't seem to be as accurate as my older models. At least it doesn't feel that way.
Last but not least, the attachment point on the rear of the tuner for the ball on the arm of the clip has already broken. There are three phalanges, just like the older models, but with one broken, the arm of the clip cannot be held in place. This renders the tuner useless, as it is contact only and that contact is via the clip and arm.
Update, 9-19-17: Adding two stars back for the great customer service, as Snark quickly replaced the broken item. Still like the older ST-2 better, but a Snark is a Snark.
