To keep it technical, dig the sweet sounding SS Sunn Beta Lead

That was a great video!

Hey, there's just some guitar tones that are simply unobtainable with conventional approaches. These tones require the legendary Sunn beta lead.

According to the wrapper, it was wired correctly, but it behaved as if reversed. This brand has black plastic/rubber seals on each end. Many caps have - end metal and + end plastic. None like that before nor since, thank goodness. But I always bring up freshly replaced HV caps on variac, one of my few good habits.
Sh!t! I'm going to start wearing safety glasses when I power up a new build.
