I'm in the " blue print " stages of a fender custom shop, meaning creating my custom p bass on paper. A couple years back I wanted to do so but I didn't have the $$. Anyway, how does this all happen. I know there's a couple different shops in the u.s., do I get to choose which one? And just the whole process of getting the bass exactly perfect and what you want done. How does the whole general process happen? Can someone be descriptive and tell me about it?
