In this video's experiment, I put the humbucker at 15 different places between bridge and neck to compare the tones! I'm playing the exact same two riffs and all open strings for all 15 positions. The pickup position is the most important design parameter of any electric guitar (maybe in combination with scale length) I'm using an Epiphone Les Paul Special II with a Lundgren PAF style humbucker pickup. The amp is a 1977 Marshall Super Bass through a 1971 Marshall 1982B 4x12 cab.
