Weights and measures (and other figures)   Updated 8-25-06

This will help in estimating the weight of your Birdsong, and will show the differences between the woods we use. As I weigh more components, these numbers will be added to & adjusted. Keep in mind wood varies from piece to piece and add a couple of ounces to account for shielding, wire, finish, etc. to any total calculated by adding the component weights. I put this page here for guitar geeks like myself, have fun! ~Scott
