Hehe, neither of these things. I am converting an EX 4 string bass...into an EX 4 string bass! All I'm doing is changing the shape of the headstock, I will have to do some cutting and pasting to the original headstock to create a paddle to re-shape. The template I'm using is from a standard 6 string guitar. As it stands it will be long enough for 3 inline machine heads, but may be just shy of being long enough for all 4. I'll knw once I get my kit and can either scan the front side of the headstock (creating a reversed image with the holes in the right place) , or trace around, that I can superimpose over my template. Then I can move the lines to fit .![]()
