It really is a great mod, as long as you like the series sound.
But it's completely non invasive (bar a bit of soldering), you still have all your original tones, and reversible if you no longer want it for any reason.
I think the best way of describing the series sound is rather than one of either pickup (call either p/u 100%) or a blend of the two (50% of each to get 100%), it's like taking the full sound of each p/u and stacking them to get 200%. Full, punchy and a slight volume boost.
It works better with some pickups than others.
I've found the wider the p/u spacing, the more the series tone is a distinct tone of it's own, and you get three completely different sounds (with a two p/u bass).
