Hi,
I was browsing ebay for violins, and I came upon this.
http://www.ebay.com/itm/AUTHENTIC-OLD-FRENCH-EXPERIMENTAL-VIOLIN-GUSTAVE-TARLE-/161047958256?pt=LH_DefaultDomain_0&hash=item257f34d2f0
What is that metal pin under the bridge foot for? It says the violin is experimental, but what is the use of that? Anyone have some insight on this?
Thanks.
