I'd also still like to know if anyone has actually spec'd the "mini-buckers" aside from taking DC resistance measurements. For instance, are both pickups wound with the same gauge wire? If not you can basically forget the DC resistance numbers since you're no longer comparing like with like.
I had some hands-on time last month with a 2013 SF-IV. My impression, through Kendrick 2112 (tweed Deluxe repro, with 3-knob reverb) and Hi-Tone (near atomic-level Hiwatt DR504 clone) amps, was that the bridge pickup was clearer than the neck p'up but not exactly weaker. Less midrange, though, much like the original anti-hums in my Bluesbird. With the Kendrick cranked into overdrive the bridge p'up cut through really well, whereas more mid-rich guitars/pickups tend to get congested and overcompressed. Into the Hi-Tone the SF sounded great both clean and crunchy. Very detailed in a Pete Townshend live c. 1982 kinda way. This amp has a power scaling-like voltage reducer in the power section so I can turn up the channel volumes without razing the neighborhood. So I liked the guitar. Felt good, played good, sounded fine & dandy.
