I bought a non-functioning Charvel Model 1B bass as a project. It had no cavity cover when I purchased it but I figured it would be simple enough to get one. The one I purchased from e-bay is very close but a little bit small for the cavity.(Advertised as a one size fits all for Charvel model number series) Does anyone know where I can find the actual cover that belongs with this bass. I think it has more than three holes as there are more holes in the recessed area of the cavity. I have added an Audere preamp to boost the pitiful excuse of a J40 pickup and need a cover plate. I hope I don't have to make one but that may be my only option.
