Hi, my Greco RB700 has been through 36 years of monstrous tone in the jungles of Thailand and the bridge pickup has fairly abruptly degaused. I've got a pretty great tech and we've come to the conclusion that the thing to do is to replace the pickups, ideally with real Rick pups. My question is, what pickups have what sonic qualities in regards to vintage and type? Hi-gain vs toaster? Best years? Modern choices? What's good, and why? Also, I was considering trying something a bit more experimental, as long as it's not a jazz pup in the bridge, since the bass is a bit more out there. Any cool ideas?
