Wound 5% less than stock neck for equal volume between neck and stock bridge while playing chords. Also good if you want a little less bass out of the neck position. De-gaussed Alnico 5 magnets.
PLEASE NOTE: Shims are used to adjust the height of dog ear pickups. Some guitars can benefit from using a shim if the neck angle on the guitar places the pickup too far away from the strings. Bridge pickups should be typically set around 1/8" from the stings and the neck around 3/16" to 1/4" from the strings. Actual placement must be set by ear and varies from player to player.
