Yes, the cluster of pickups is not from when the logos and presumably some other pickups and electronics were installed.

I don't think we did the work in the cluster picture you posted in reply 4. I'm not sure if the Bondo that was inside the bass was put in at the time of the cluster of pickups or not, but it was there and had to be dealt with. First time for everything!

These are Skylark pickups (like a wider HB pickup with a rounded mounting flange) with 20th Anniversary electronics - same layout as a Series I but the *exactly* same sound of course. Dan's bass came out great.

So I think this was

1. Alembicized in the early 1970s

2. Things happened to this bass in the 1980s that weren't done here

3. Alembicized again in 2021.

So is HG Humbucker Guitar and HB Humbucker Bass?

Is there a difference between a guitar pickup and a bass pickup?  Just magnet size or something else?

Do guitar pickups work fine in a bass?
