I've not really ever set out to compare them with other pups.
I installed this set in in bitsa 58 P that I built. They were exactly what I wanted for the bass at the time, they gave the period correct sound, pretty much.
I played half a dozen or so gigs with them installed, using both flats and roundwounds. It sounded like a p bass should.
I've recently revamped the bass again and wanted a more aggresive sound to suit the current band, my wife treated me to a set of Seymour Duncan quarter pounders.
I should probably keep the 62 R/I's as I'm bound to want them at some point for another project, but I'm really trying to make a concerted effort to not horde and store stuff that will come in handy one day.
