Depending on what type of pickups you use, ie: staggared (pole pieces/magnetics) on a single coil or humbuckers. Pickups to close to strings can cause a muddy sound. The magnets draw your strings through its polarity amplifing the vibration or ocillation of the strings. The farther away the more magnetic draw hence clearer tones.

Guitar manufactures have recommended pickup heights published (I know that atlease Fender does). Check out the manufactures site and look up for users manuals under set ups.

Hope this helps.
