I thought this would be a fun and useful thread to discuss the "old school" methods of using relatively low output pickups in higher gain applications, (perhaps not chugging metal gain) much like our heroes did in the 60's and 70's before there were many high gain pickup options.
I thought we should first define what a low output humbucker is.

Vintage Gibson Humbuckers Specs:
1956 – 1957 (“PAF”): Long (2.5”) Alnico 2, 3, 4 and 5 magnets used randomly, brushed stainless steel cover, *no* PAF sticker, automatic traverse wound with manual-stop (until bobbin was “full”), #42 plain enamel wire (purple/maroon), individual coil ohm differences, black leads on coils, ohms vary from low 7k to high 9k, black PAF-style bobbins (“square in circle” with holes). PAFs first installed on Gibson lap-steels in ‘56 and then guitars in ‘57.
1957 – 1961 (“PAF”): Long Alnico 2, 3, 4 and 5 used randomly (A2 most common), nickel cover, “Patent Applied For” sticker, automatic traverse-wound with manual-stop, #42 plain enamel wire (purple/maroon), individual coil ohm differences, black leads on both coils, ohms vary greatly – generally between 7k and 10k, black and cream (early-’59 thru mid-‘60), all bobbins black again by late ’60, PAF-style pickup bobbins.
1961 – 1962 (Late “PAF”): Smaller (2.37”) Alnico 5 magnet used for remaining production (all transitioned by July ’61), nickel cover, PAF sticker, automatic traverse-wound with manual-stop, #42 plain enamel wire (purple/maroon), black leads on both coils, individual coil ohm differences, ohms averaged 8.0k by ‘62, PAF-style bobbins.
1962 – 1964 (“Patent number”): Alnico 5, nickel cover, “patent no.” sticker (mid-’62), polyurethane wire (starting ‘63), black/white lead wires, “auto-stop” winding starts circa-’62, PAF-style bobbins, usually 7.6k – 8.0k ohm.
1965 – 1967 (Late “Patent number”): Alnico 5, polyurethane wire, “patent no.” sticker, bobbin wires white, Chrome cover (starts mid-’65), more durable and flatter bobbins with no “square in circle” hole circa-‘65, ohms usually between 7.4k – 8.0k. Gold-plated PAFs used in arch-top electrics as late as 1965 – “Varitone” guitars had gold-plated pickups with one pickup having a reversed magnet. This pickup style was used far less than nickel-plated pickups, thus inventory lasted thru 1965.
1967 – 1980 (“T-top”): “T” on bobbin top, Chrome cover, Alnico 5, polyurethane wire, automated winding begins ‘65 – ‘68, some ’69 – ’73 pickup covers embossed “Gibson”, “patent no.” sticker on baseplate ’67 – ’74, (patent number metal-stamped beginning 1974), ink stamp with date ’77 – ’80, ohms average 7.5k – consistently reading between 7.3k – 8.0k.
So, from this article, it would suggest that "low output" can be defined as pickups being in the 7.0k to 8.0k ranges. While many other factors - besides DCR will determine a pickup's output - I'll suggest we use the DCR values for the purpose of this discussion.
