Ah, cool, I actually like that as a concept, that way one band foesn’t have to feel like the 2nd fiddle.
I was one of those early leaving people haha, I went specifically for Gojira and frankly have never been huge into Mastodon, so when they closed I used it as an opportunity to get ahead of traffic. The pit for Gojira may have also factored in, I could barely move the next day.
Not just guitar audio! I own a tube amp for my guitar and 2 tube amps for driving my higher-end headphones! They are neat little pieces of electronics history, not just in how they run, but also because most of the best tubes are old military surplus. My oldest pair are from 1945 and were made for early army/navy radar systems.
