Hi there,
I was test-driving a classical guitar yesterday, which had obviously been used for some heavy-duty flamenco playing. There are considerable scratches in the French polish (spruce top). Now, the scratches outboard of the treble strings are perfectly normal and expected. What confuses me are multiple deep scratches on the top, between the rosette and the bridge, which are UNDER the bass strings. The scratches (divots, really) were mostly between the 5th and 6th strings, some between the 4th and 5th. Almost none outboard of the 6th string.
I'm at a loss to understand what sort of RH thumb technique would cause so many dings in the places I've described? Any insight is appreciated.
David
