I recently purchased a set of 57/62 pickups complete with wiring and scratch plate, (all set to drop into the guitar and to merely solder the jack plug in). I recently had a bit of a bad experience with AxesRus and one of their pickup assemblies where on receiving the assembly the vol knob had been put into the bridge tone position...when I eventually installed the bits all the selected pup variations were all wrong sound wise and so AxesRus took them back to inspect them. When I eventually got the assembly back I wasn't happy with the result and so gave it up as a bad job and hence the purchase of the 57/62s.
The 57/62 pole pieces on all three pups had been very low set on the 1st and 2nd string and the whole pickup had been adjusted to be sitting high on the scratch plate,(obviously to compensate for the inevetable drop in volume). After installation I set the treble side of the pups to be even higher in order to get somewhere near a decent volume on the first two strings- the third string now being a tad bit strong, however I'm pleased with the set as there are much more harmonics to hear and the bridge pup gives a good sound (to my ears)
I do wonder why Fender don't sort these anomalies out in this day and age instead of just leaving their pups as they were back in the day of 7.5" radius necks.
Incidentally I wouldn't call the 57/62s a 'modern' set of pups as they don't imitate the sounds you get from a current day Strat where you get a much ballsier sound from the inbetween positions- here the sounds are much more bassy.
