‘Can you make a BeBop 5 with 17mm string spacing?’ No problem. Or.. wait a minute.

That means I need to design a narrow neck. And have a custom bridge made. And custom pickups with the poles at the right spot under the strings. And then my tuner-layout changes, so I need to change the headstock. And the neckpocket in the body must fit the narrow neck, so the inner  curves of the horns of the body need to change too. And then the pickguard needs to change too… ‘And can you make the body a little smaller?’ …why not, that was the only thing left that I didn’t have to change yet. Anything else? ‘Yes, a 3-piece neck like my Elevation, blackwood fingerboard, Aero pickups, closed covers, black hardware and a ramp between the pickups.’

Change the stringspacing and you wind up redesigning the whole bass. The last step was to give it a new name too: the Glenn Gaddum Jr. signature BeBop. The bass was a work in progress for more than a year. Glenn tested the demo-bass for a few months in different situations, and came up with some details that he liked to see changed. Eventually I built a final version, and that is the one you see presented here. For technical details like dimensions of the neck scroll down to the bottom of this page. But before you do, check the demovid, if you haven’t already.
