I really like the fact that they tweaked amp settings for almost each song. I think it adds a subtle character to each. I'm not sure how common this was back in the 'old' days, but I think it is a reason why a lot of newer albums sound so generic to me when they get their guitar tone setting and it stays
exactly the same throughout. Cut'n'paste tone for an album gets boring real quick. I think it's why a lot of newer music and recordings,
ESP using digital IR's, I don't enjoy as much, it's too perfect and exactly the same over and over pretty quick. No real personality. I get that consistency is needed, but those little subtle differences add to the end result.
Add in the factor that many bands songs on albums run similar tempos from song to song, but I guess that's a natural thing between the band dynamics that they usually play and feel comfortable with.
At least thats my personal theory why some of those older era albums have such an enduring appeal for me. The little differences reward repeated listening. The more cut'n'paste the sonics are through the album, the faster I tune out and don't go back to them as much. I'm focussing here on tones and such, not about the greater songwriting factor and such.
re: 5.98 EP. I like the rawer sound on that album. Obv down to the lack of production, as stated on the album cover. It sounds much more like straight IIC++ without too much over-polishing. Get a good raw tone for each song and knock out the songs. I love Jasons bass tone and prominence in the mix. If only his bass had sounded like that on AJFA it would have been more killer.
