I was looking at the Les Paul Jr. Tribute double cut bass (30-1/2” scale) with one “bassbucker” pickup. Can anyone school me in this pickup? Is it like the kind that they used to put on the SG bass? I can’t seem to find much info on it, on its design/construction, to know what it might sound like, other than they say the bass is warm sounding and I’m guessing not a lot of pop. If I wanted to swap out the pickup is there a drop in replacement for this type or is one that doesn’t have aftermarket options? Thanks in advance.
