I bought a pair out of a r4 that really sound good in my black p90 les paul standard. When I got the guitar, someone swapped em for cheap pups and messed with the wiring. I ended up with new pots, caps, switch, braided wiring and did it 50's wiring. I love em. I did buy an antiquity from a friend for the bridge prior and wasn't jazzed about it. I think stock p90s are great! Not sure of the year, but owning a tribute 50's from 2010 I automatically wanted stock p90s for this one. Hope that helped
