Ok, here's the thing; It's not so much 'what you can't have', but more of a case of 'anything goes'. Your own body shape? Sure. Chrome plated flying V bass... with Multiscale, and active pickups? Sure. Want to select your own timbers? Not a problem. Specific scale length? Easy.
You can start with one of our own body shapes, or design your own. We like to think there are no limits to what you can have. Just your imagination, and a dream, is all it takes...
