What are some things that you strongly wish were common knowledge?

[Rev. Rye]

Here’s a few to start with:
1) As far as guys go, foot fetishists are pretty harmless.
2) Instead of just listing DC Resistance for guitar pickups (something that’s simultaneously nigh-on universal for pickup manufacturers and remarkably useless in telling you what a pickup sounds like), pickup makers should also list inductance and resonant frequency (with 470pF capacitors to simulate the length of the average cable).
3) Guitar speaker sensitivity is as critical (if not more so) in knowing how loud an amp can be as wattage.
4) Honestly, I could sum up a lot of things with “anyone with the slightest interest in the building blocks of guitar tone needs to subscribe to Jim Lill yesterday.”
5) Even in the age of streaming, physical media is still important. They can take Uncut Gems from Netflix and move it onto some other service you’re not subscribed to, but they can’t take away your Blu-Ray.
