I thought the point was to pick out differences and decide which we like better...as per the first post. In a live mix, no. In front of your amp playjng, yes. With some pickups absolutlely.
Then why the remark about greatest sonic palette due to wiring harnesses? 2021 has the most treble. Audible differences one can hear.
Otheriwse everyone picks the only available pickup on the market as it just wouldn't matter.
It's just intended as a fun sonic exercise.
Have you ever tried the 21 tone Jimmy Page harness?
It's remarkable!
In a session environment for hire, the 21 tone harness brings a lot to the table, series, parallel, in and out of phase, etc.
