I have a Ibanez SR250, and I wasn't careful enough with the pickup adjustment screw heads so they are in danger of stripping out and being unremovable. I'd like to replace them with the exact part, it seems to be a specialty screw so something from a hardware store won't do it, I'd like an exact set of 2 longer and 2 shorter screws that came on the bass. Is it possible to get what I am seeking? Of course guitar center the place where I bought the instrument claims they can't order parts, this of course seems ridiculous but is totally exemplary of their lack of customer service. Maybe I should just return the bass with no explanation.
