Unfortunately, it is mentioned in the descriptions nowhere, that the soundhole of the guitar has a diameter of 100 mm +/- 3
must have!
In one of my guitars I could but may find halfway dranhalten more than reconnect and have that the tuner works fine in! And is very accurate.
If anyone is interested - was made of / the Rimpitch in Vietnam.
In the description, is that the rubber may alter the surface, if you leave the tuner permanently on the instrument. But the attachment is a fumbling, because you have to let off virtually, otherwise the part also makes no sense yes.
Grab the Anschalter sitting quite deep and you have to "in the string" (ie at high e '' pass), so you can switch off and other him. It may be that this is easier if the diameter is larger overall and it was a bit cramped with only my 82mm.
In than described also is that the tuner works with vibration, but also responds to loud noises in the area, but that should have no effect on the result.
Give for the brilliant idea and actually very good tuner I give 3 stars (not bad).
Personally, I was very annoyed that was mentioned with the diameter nowhere and I had to send him back for that.
