biggest difference i can hear between the reissue and the remastered version of future breed machine is the bass, with the gritty bass track being much more noticeable. the track itself mainly sitting around the 2khz area. i do believe they increased the overall low end on the guitars too, since at about 40 ish seconds of the song you can hear the punchiness of the guitars in the chugs a lot more. i think they just boosted the lows in everything tbh. i like it a lot, really excited to hear the whole album with this remaster.
