one of my fav you tube channels right now. He comes out and says its Corgan, without really saying it. "just worked on some gear from 1979!!" Who else uses 2 strategy 500s these days? the real gear nerds can guess it right away, even without the 1979 clue.
i gotta watch these on 1.5 speed, but i've learned so much from this guy. I wish guys like him, or brads gear garage (australian dude who fixes gear live), or the guitarologist, or you tube in general were around when i was trying to teach myself how to do amp work back in the mid 2000s.
would have saved me some money, grief, and time.
