I love my Thumb 5. But because of PU configuration, I kinda miss the fatness a neck pick-up would bring. I was thinking of adding a neck PU and maybe, while I'm at it replacing the 2 MEC and the on-board preamp (thinking about those Villette passive). I was thinking of a system where the two existing bridge pick-ups would be wired a la humbucker so I could have a blend between those two and the new neck PU. What do you guys think?
