Available as an option on Fralin Alnico poled Stratocaster bridge pickups, the Base Plate may be an interesting upgrade to try with other brands of pickups. Gives you 10% more bass without affecting the mids or highs! Simply installed on Alnico poled pickups; see Fralin's website for detailed E-Z installation instructions. Basically you just put a thin strip of masking tape over the bottom of the magnets, stick the ferrous Base Plate to the magnets, extend and solder the black ground wire on your pickup to the preapplied solder pool on the Bass Plate, hit it with a hair drier to flow the wax a bit to tame microphonics, let cool for three minutes and you're in business. There are oversize holes in the Bass Plate to permit the two pickup height adjustment/mounting screws to pass through. Brand New. Genuine Fralin. BONUS! We include more than enough cloth covered hookup wire, some audiophile silver solder and some real Fralin pickup wax. You won't find a better deal on the Fralin Base Plate anywhere on the planet.
