I'm a newb at screwing with my bass, but I was wondering. I wanna take off my old knobs whichi just slide off and would it be easy to take a few dice, drill a hole in them and put them on? If the hole is tight enough they shouldn't slide rite? I'm really frugal, I just don't wanna pay american prices for a set of dice knobs than pay shipping on top of that. what do you think?
