The Lindy Fralin Partial Tap Resistor is a type of sub-modification that works with the coil-splitting humbucker modification.
Why use a Lindy Fralin Partial Tap Resistor?
You can only coil-split humbuckers, which means that you can use a switch to turn off one of the two coils that make up the humbucker. The resulting tone is usually much less powerful. The guitar will drop in volume, but the tone will brighten. Your humbucker will take on the characteristics of a single-coil pickup. Notes will be crisp and clear, but you will lose humbucking capability, and noise will creep in. This ingenious mod by Lindy Fralin opens it up to make it even more useful.
