Please forgive my ignorance, I'm from the "other side". I've got a morbid curiosity about the dog house, and I'm wondering why DB strings are so expensive. It seems inconceivable to me that four strings can cost $200 and more. Is it economy of scale? Is it a labor intesive process? Can they only be made from unicorn mane? What gives? I did a search, and came up with nothing. Help me out.
