I am VERY curious about the new fender pawnshop bass VI, with an added humbucker in the bridge position and a whammy bar, and a lower price tag than going vintage, it is very tempting. Even vintage recreations are going for top dollar, this new version looked unique I am very interested in trying a bass tuned from: the standard low E to high E, (like a 4 string bass with two added high strings) My question is this, how thick gauge can we go on the lower strings on this? I would like the low E and A strings to feel thicker than their usual gauge, I know I can't expect to get the same gauge E and A as a 4 or 5 string bass, the spacing is tighter.. I realize that. how much thicker would the string spacing and nut slots allow? and. if we widened the slots in the nut and saddles, could we take it a bit heavier? (without compromising string spacing) anyone have experience w this?
