Heritage use 3 different headstock sizes. Large for Jazz guitars, medium and small for most electric guitars. I wish I had found that out sooner. My last custom build, the Heritage Millennium SuperLight, should have had a small headstock but I had them use the medium size because it looked more balanced to me. Don't forget Heritage had a number of unconventional guitar models that used completely different headstocks, I'm looking at you MarvBird.
