Question:

"admira asks, "Hi. I watched Steve Eulberg say it's easy to drill holes in an acoustic guitar and screw strap buttons in it. I have a classical (nylon string) guitar, and I want to know if there's absolutely no problem doing so. Can't it damage the sound of the guitar or something like that? In addition, I noticed Willie Nelson uses a somewhat strange guitar strap, on his classical guitar, which attaches to the bottom of the guitar's sound hole. Is this considered to be a better solution for a classical guitar? Could it too damage my guitar somehow? Thank you very much, Eran.""
