Well, I just installed my new Quarter Pounders. They sound GREAT ! I put em on a cheapo Bass. This was my first install. The only problem I had was that the covers on the pups kept sliding off. They are neccessary to have on since they hold the screws to hold em in and adjust the height. Anyway, the only way I could keep the covers on the pups was to put a few thin slices of duct tape on the bottom of the covers taped to the bottom of the pups. It works, and ya cant see the tape with the pick guard in place. But I was wondering.......it just does not seem like I should have to use anything added to make them functional. Is this normal ? Anyone have any thoughts or experience on this subject ?.............thanks
