I've re-installed the new full set of pickups that Mica sent to me a couple of years ago when my '77 Series bridge pickup died. She and Ron thought I should just replace pickups both for consistency. I've found another '77 bridge unit since then to replace the dead one, so I've been playing it with a full stock vintage pickup set installed. It sounds great, and nothing wrong with the sound. But, I just heard a past live recording on a cell phone captured back when the new pickup set Mica sent to me was in the bass, and I gotta say that the new units are pretty amazing in the mix. Definitely aggressive and rocking-sounding. So of course I put them back in, and wow, lot's of detail and power coming from the modern set. I wanted to stay true to the '77 vibe with the older original pickups, but I'm happier with the bigger and beefier sound of the newer set. There's a lot more information coming out of the newer set, to my ears. My current custom build will have Fatboys, and I bet they are pretty close to what I'm hearing from these modern Series pickups.
