In our Unbucker, we wind the screw coil stronger than the slug coil. This makes the pickup sound a little more single coil, but the best reason to do this is for coil tapping. When tapped the stronger coil is active as opposed to half a pickup. Our best selling set of these is 7.5K neck (4.5-3) and 8.5 Bridge (5-3.5) 3 conductor lead with a Vintage Hot reverse middle in-between. (Humb.-single-Humb.).
Combining the two coils gives a total ohm reading or approximate output to compare to normal humbuckers.
Stock Set as above – 7.5k Neck, 8.5k Bridge.
