Great comparison as always! The 57 doesn't sound bad. Buuuut I still prefer the 81 over it. I'm not sure if I like the 57 better than the JH though. They both have their thing going on
First impression was that the difference wasn't that big but that I preferred the 81 to the 57 to the JH. Listening back on monitors, 57 and 81 sound similar with the 81 having a sharper pick attack and slightly tighter low end. JH is sounding similar to the 57 but with a looser low end.
I'm guessing the amp was dialed in for the 57? A less thick guitar tone might tell more as well.
