I've just checked the info that came with my Riff Raffs and Alnico V is quoted for both. I would go for a Riff Raff neck if you want higher gain clarity and definition. Alnico V is best for this in my opinion.
Thanks Dave, another snippet of info for my BKP memory bank (we need those tone charts and specs on the website!) :D
FWIW, I've found that I like the warmth of AII or AIV for neck humbuckers, and the gnarlier tone of AV for bridge. I find AV a little harsh for a neck pickup (e.g. the Duncan 59n, which I never get on with). Having said that, I wouldn't choose AII for a
bridge pickup.
But then I like a very warm, round neck tone so that's very much a personal opinion.
Tom, now that you've
nearly decided what to go for, it's probably worth consulting Tim to see what he reckons would work best with the Nailbomb. :)
(
Edit: I don't
remember hearing any neck Riff Raff clips, but there are probably some in the Players section, somewhere.)
