With a strat you'd typically set a sound for the neck or the middle pick up and when that sounds great you'd need to reach over to amp to adjust tonecontrols when you start using bridge pick up and then bridgepick up is anyway not hot enough to compete with the next guy's guitar or your own that has humbuckers,P-90's ,Filtertrons and what not but anyway out of the bridge position on a a guitar you'd like to get the rock sounds. Now you set this as close as you can,and maybe you'd even get a hot bridge pick up and that sounds nasal and then you might just carve your guitar to fit a humbucker and you can get the sounds but it's nolonger a strat and you miss the standard sounds you got from the bridge pick up for the occassions when you record a spaghetti western soundtrack, oh well, but then neck and middle pick ups don't sound so good anymore. The design of a strat dates back to the 50's and back then you'd double on bass and it was considered a good thing to be able to go from deepest bass to highest treble; however the modern guitarists (and maybe those in the 50's too)might more be interested in changing the midrange peak that changing pick ups give without too much change in treble and bass. Keeping these things in mind the BJF/Lundgren set was designed to give a strat a powerful output that would compete with higher output guitars to allow playing near any kind of music on a strat as also originally intended for the instrument while this without having to compensate on amplifier for changing pickups. Important though to set the power of the set so that a classic sound would result albeit somewhat more contemporary. Technically this is done by viewing each pick up for what it does and in combination with its sibling and further observing loading of resonant peaks to make a somewhat equal response from each pick up throughout switching sequence. The set comes either with a reverse middle pick up for hum cancellation in position 2 and 4 or with same polarity for all pick ups for use with silent systems. The attached yellow and blue components and schematic apply to standard wiring strat with no tonecontrol on bridge pick up; when a tonecontrol is wired to bridge pick up omit the blue component from wiring.
