I think this song is one of Myung's more interesting bass performances of the past few years (up there with "Outcry", "Breaking all Illusions", and apparently he's got a good one on "Behind the Veil" from the upcoming album according to a pre-release review), mostly because he goes through three distinct sounds during the song, each for different purposes. Two of them I've got figured out pretty simply, but the third (or rather the first) is confounding me, and I'm hoping someone can help me figure out what kind of effects he might be using to get that sound. Bass track for reference
The "basic" sound you hear during most of the song is pretty obvious: overdrive, steel strings, hitting with Myung's attack. At 38 seconds in he cues a fuzz-wah that sounds remarkably like something Cliff Burton would have done for playing the main riff. I'm going to assume this is just fuzz and a wah, but if anyone thinks otherwise please contribute. Neither of these sounds are what I'm looking at.
I'm talking the very first sound, the one in the intro. I've never heard a bass sound quite like it. What's he doing there?
