"no fears dude!!!"
Here is the section:
The distance between the pickup and string is a very important factor for output and sound.
As a general rule for the bridge pickup - put a nickel on top of the pickup under the high E string and play the highest note on that string. Adjust the height on that side of the pickup till the string touches the nickel. Repeat the same with the low E string, but use two nickels on top of each other. If this gives you too much output, you can reduce the height slightly. Don't forget that twice the distance will reduce the output by about 60%, and the sound will lose some lows. NOW, you can adjust the neck pickup to match the output of the bridge pickup. For the sound test, use stage volume.
