I’ve never owned a basswood guitar, but I can attest that the Holy Diver sounds amazing in an alder Super Strat with the same trem system that is in the Charvel GG. I would think the Holy Diver should work as well if not better in the Charvel compared to the PRS. If you wanted a rounder, less aggressive tone, the Crawler could work. For singlecoil, I’d go with the Irish Tour, it pairs nicely with the Holy Diver and is a vintage hot pickup, so it should work for your style. No idea on neck humbucker since I haven’t owned any.
