when we had our used/vintage music shop in Huntington Beach Ca. just around the block from many companies (amp/guitar/parts), a guy used to come in from a very well recognized pickup maker, to see what we had, and just hang on his lunch break.
he sat down by a super reverb, plugged in to the low (2) input of rev/trem channel, and plinked around. I asked him if he preferred the lower input, and he replied that that was the same model of amps that they, (the famous p.u.maker) auditioned p.u.s with, but was unaware there was a difference in inputs, "we just plug in to either input". further conversation led me to believe no one at their shop knew different.
Not trying to put them down, as much as just finding it so funny that a co. so well known, and having product in a famous guitar players axe, who is known for 'woman tone', could possibly not hear/feel the difference in inputs.
And while i've not been a fan of their pickups, I freely admit that i have one in middle pos. of one of my Strats, and when in 2 & 4 position, mixed with other pickups, it consistently gets praise towards being one of the best sounding newer (MIJ 3bolt) Strats people have heard. I guess low powered opposites attract. only other change is no cap on mid pu, just tone on neck & bridge. maybe something there, if someone is interested.
oh yeah , other pu"s are Jackson single from old days?, cloth wire, 5.8-9,or 6Ks neck, and Seymore little 59, series/split/parallel in bridge. middle is possibly low end model, not sure of AG markings.
so if you have time, try out those old 'crap' pu's. give em a chance, my buddies favorite strat pu came out of Mex strat, and he has Andersons, Tele Nashville's, great American guitars, but that one Mex pu. is special/or just works w/his setup.
