I have an acquaintance who wondered out loud what would be involved with switching out the Esquire pickup with a P90. Forgive me if this has been discussed previously, but I did bother to search the forums first. There seems to be next to nothing online about this, but I likely am just not looking in the right place. I simply do not know where to begin to answer as this is not my area of special interest, but now my curiosity is piqued. So, I defer to my friends on TDPRI. Has anyone swapped an Esquire pup for a P90? What did you change? What did you keep? What absolutely doesn't work? Cheers!
