This is even crazier when there are 2 rows of screws(both coils have adjustable screws). I think that you must set this up loud enough and with a not so overdriven sound to get the best from the string vibration and clarity when setting the screws. However, the adjustments showed here work great for my Les Paul guitar even with 9-46 strings in normal tuning. It sounds just more balanced and fat. I will be experimenting with this in all my guitars, starting from these references and going further by ear. The only guitar i am leaving out is my Carvin V220 with 24 screws in each HB!!!!Mercy......
Why doesn't Eventide produce a thing like a pole-hight adjustment "box of pickups" to put us out of misery????Of course if it costs $$$$$ is another thing.....
