I was (and still am) a huge Pestilence fan back in the day. Got Malleus the first week it was out, and by the time Spheres hit they were one of my all-time favorite metal bands. I still remember the night this song hit Headbangers Ball and instantly thought "WTF, the guitars sound awful!" but still loved the song, Martin's Vox and Patrick's riffs. A week later I discovered Bolt Thrower and that was the end of Pestilence being my fave band.
The tone is like nothing but pick sub-harmonics squeezed through a way-too-tight hi/low pass filter. Not sure if it's the producer who screwed it up or the guitar players bought all new gear and didn't know how to dial it in before recording or what... but man the guitar tone is awful.
What song do you love that has a guitar tone you hate?
