I wonder how will increasing or decreasing my humbuckers affect the sound(like tone sutain and stuff) of guitar are there any standard heights or measures? I haven't changed anything now guitar is still like ist was when it came out of the box
Raising the Pickups will make it hotter.
IDK, I usually just adjust them till I like the sustain and tone I get, not really any standard measurement for them that I know of. Usually the higher up they are the less sustain you have but more output.
3 to 5 mm is a good place to start, to close to the strings and the clean sound will be distorted, to far away will be kind of dull sounding.
