In the expanded version of "Slaughter Of The Soul" by At the Gates, Tomas mentions in the liner notes the equipment used by them to achieve that sound:
Boss HM-1
Boss MT-2
Peavey Supreme 160
Anders Björler's fucking home-made quadboxes
Has anyone got a clue about the levels in which Anders and Martin use on the album? The ultra-bassy sound is bloody difficult to achieve.
