Advice n ideas from the cognoscenti please! Wanna fatten up my thumb b/o 5 n after an initial enquiry it seems I can't replace the 2 pups with a MM style due to routing size etc, so was thinking if I had a neck pup put in n had the 2 existing pups wired as 1 with a series/parallel switch it would yield the best compromise with a beefier tone n minimal outlay n routing. Your thoughts? Thnx in advance
