Hey, i have a question about straplocks in a bass. I recently installed a pair in my new Marcus Miller, and every so often i have to tighten them, as the screw comes loose. Is this perhaps because i used the thin pad that came with the factory strap buttons as opposed to the thicker ones they came with? Is there anything recommended? Because i have no desire to drill a new hole like i had to for my starter bass. BTW, the straplocks are Fender, which are exactly like Schallers, just rebranded. Thankyou for any help.
