Binding and Purfling are a beautiful and functional accent to a finely made guitar. I tend towards simple and elegant binding schemes on my instruments and I consider solid wood binding and simple wood and fiber purfling to be standard.
Currently I am in love with multi-line purfling, black/maple/black and more colorful options are available. Recently I have been working with Spanish cedar (on right), mahogany and fumed eucalyptus purflings made in house. I think it makes an understated and beautiful binding scheme.
I am also a real fan of making binding and purfling from the sides of a guitar and using contrasting laminations and purfling to bring it out. Here the sipo binding and purfling, cut from the sides of this guitar, create a beautiful and smooth transition from the sides to the top.
Binding schemes can also be matched to custom rosettes as pictured here. This RB-000 features a rosette made from the same purfling as was used with the binding. Because this was made from the sides of the guitar, the rosette, binding, and purfling match the back and sides of the guitar perfectly.
