That IS awesome. SIT is my fav Maiden album of all time thanks to its production and engineering. I love the space created by the tasteful use of reverb. I believe this record uses reverb on the master, which is something I do, as well (as inspired by this album).
For those interested in getting these lead tones live, the discontinued Mesa Silhouette does these to perfection. I had a Deuce Stage II and it just nailed the tones on this album. It's the only amp I've owned twice lol.
Anyway, great playing. Enjoying your vids.
