Hey, I am planning to build my own bass soon, with the aid of my dad, but I need to know the specs of the instrument. I am planning to reproduce a Vintage 5-string Sadowsky. I searched around their site for specifacations on the bass but couldn't find any. I was wondering if anyone here could tell me info on this bass. The neckwidth, nut width etc. Thanks in advance! Picture of bass in question.
