pardon my noobliciousness, but here goes: These questions relate to sadowsky basses 1) is there really *that* much of a difference in the sound between a p/j pickup config and a j config on a sadowsky? can someone please describe this to me 2) is a maple neck (w/ maple fingerboard) going to be noticeably briter than a rosewood fingerboard sad? is this going to be "undoable" to a non-afficianado using the active eq w/ a little treb cut/bass boost? 3) At the end of the day, is there that much of a difference between a p/j sadowsky and a p/j glaub or a j/j sadowsky and a comparable lakland US? There seems to be a pretty big price difference and not too many people out there expressing a real tone/playability difference. 4) What does a nice condition used 4 Sadowsky string go for, I think I've been bit with the GAS bug!? Thanks!
