Modelled to replace GHWT guitar battery boxes that have been destroyed by corrosion or other factors. There's no brackets to fit contacts in as finding the right contacts would be hard and so would wiring it as the original. Instead, this model is supposed to simply hold any solution for batteries that is desired. Holes may have to be drilled afterwards to route cables.

There's also a second model available with a 1mm wider opening to accommodate the battery box I bought which is 32mm wide instead of the original 31mm (this is the version in the picture).
