I'm looking to improve an old spare bass I have . Someone recommended the G&L mfd pick ups . I'm not sure what to get really. I'm new to modding so im not sure what to do if it dosnt fit. And he also asked me to install a parallel/series switch . Can someone briefly explain what would this switch improve and do I replace it or add on ? And do I replace the mfd with my current pick up or add another ? Help a noob out please
