Dave Burrluck answers some questions, the first addressing one of the most fundamental aspects of your instrument – string spacing. And while plenty of people will quote you their preferred nut width, do they know what the actual string spacing is? To clarify, the string spacing is measured between the centres of the two outer strings [pic 1, below]. Irrespective of the nut width, it’s the string spacing that determines how much room your fingers have. Historically, Fender used a wider string spacing at the bridge of approximately 55mm, and Gibson used a narrower spacing closer to 50mm.
