I got some Seymour Duncan's to outfit one of my 90's Ric 4003's and they were very difficult to install! They didn't quite fit and they screws were all the wrong size, relative to the original pickups! Any idea why they're like that? Similar experiences? On the flip side, after I fitted them right, I think they sound a bit better than the originals, not just cutting hum, but a bit smoother, yet still crisp. I dig the growl of the OG pickups for a few things, but a little too harsh sometimes. I was wondering if anyone knew of other pickups designed for the Ric, and what their take on the Seymour Duncan replacements was.
