[pianotech] GH1 - pitch lock?

[John Formsma]

The first thing that comes to my mind is will another technician realize
the Pitchlocks are there? It's fine as long as you're the only one tuning
it, but someone else might not notice them at first.

What about putting them close to the agraffe so they're more visible?

I've had good results with using Pitchlocks on some Steinways with lots of
front duplex noises. (On Steinway D's the C6-E6 area can be pretty awful.)
And have used them on bass bichords a time or two.
