SJMB 3 Stratocaster passive mid-range booster $112 Sound sample

No soldering required, and no need to even look at a wiring scheme. In fact, there is no wiring scheme. Unscrew the standard Strat jack, cut the wires from the Strat jack, insert them into the screw terminal connectors of the booster jack, tighten the screws up and screw the booster jack into its place. Installation takes two minutes and doesn't require any experience in working with guitars!
