SNARK Studio H.Z.
I stopped in to a local music store today and found a new headstock tuner available from "Snark" that is very accurate and also measures in HERTZ Frequencies if you want that. I personally have many different tuners, including the earlier Snark brand. This one seems to be a step above.
On this forum, we have had many discussions about tuning the guitar in slightly adjusted pitch. That is why I thought I would post this picture and info.
Happy playing!
Bart
