When I ordered my first set, I asked MJ to wind a standard spaced one as a neck humbuker....its pretty sweet, has a lot of characteristics in common with my Fender strat neck single coil, but still has the power of a humbucker. Its not quite as "glassy" as true single, but the mids and lows are very similar in response.
Back on topic...if this pup is still out here this coming Friday, I'll probably buy it (the Crazy 8), I think I am addicted - and I'll have to get another guitar for it.
