I got a pair fo kick ass 50's P90's I am going to put in one of my LP deluxes... This 73' GT I have has some of the best sounding mini's I've ever played especialy the neck PUP...pure CCR early days when he was playing his customs... Has anyone here swapped just one pick up out and left the other...such as perhaps I should leave the neck PUP in and swap out the bridge PUP with the P90?? Or is it better or more balanced, swapping both at the same time?? Does it make a difference and can the PUP's of an LP be out of balance so to speak if I was to change one and not the other?? Thanks!!
