I enjoyed it for sure, I hadn't heard this band before and now I'm a fan, which is awesome.

It wasn't super difficult, though I was stumped in one place for a bit but eventually got through it. Luckily there are a couple of live videos available from before the song was rewritten to be much more simple in the 2000s (for example, in the newer version, most of the riff complexity is replaced with simple 1-finger Drop D power chords, which was useless to me as I was tabbing the O.G. version). It was fun researching the song and trying to catch a glimpse of where certain riffs are played on the neck etc. Kinda hard when the videos are from ancient VHSes from the '80s 😆
