So, just the pot through-holes in the "P bass" guard don't align with the control rout(such that the guard's holes can't be used for the pots)? Or does nothing on the body line up with the guard(like pick-up, neck-pocket, etc.) requiring a completely different guard. If nothing is of Fender dimensions, you could do a template out of heavy manilla(like a file folder), complete with hole locations fairly easily. Then, any guard maker could create the actual piece. I did the drawing(a sort of pencil-wipe transfer) of the lower bout of my FenderBird and mailed it off to Tony(Pickguardian). I let him choose the hole locatons as I had none in the bare body and used the finished guard as the guide.
