Dunkelheit amp settings — Catalyst line 6 100-watt, 1x12 modeling combo amplifier that features 12 Helix-derived amp voicings and 24 built-in effects.

The Burzum guitar tone for “Dunkelheit”, dialed in for a Catalyst line 6 100-watt, 1x12 modeling combo amplifier that features 12 Helix-derived amp voicings and 24 built-in effects. with a PRS SE Hollowbody II blends the resonance of a hollowbody with the stability of a solid-body. Studio version, Filosofem (1996) — recorded with intentionally degraded signal chain (home stereo amp + fuzz pedals, no guitar amp)

Original rig

Westone Spectrum LX guitar → old fuzz pedals → home hi-fi stereo amplifier (not a guitar amp) — headset microphone for vocals

Thin, icy, trebly wall of distorted fuzz with no low-end warmth — deliberately lo-fi and distant, like hearing guitars through a broken radio

CRITICAL — the original tone IS a fuzz into a non-guitar amp. Use Catalyst's built-in Heir Apparent or Arbitrator Fuzz effect. Set Tone LOW to cut fizzy highs while keeping the brittle character. If no fuzz available, crank amp gain to 9 and accept it won't be authentic.

Level 7 · Tone 3 · Fuzz/Sustain 8

Why these settings

The original used zero guitar amp coloration—just fuzz into flat hi-fi. Your Catalyst is inherently warmer and more defined than that broken-radio sound. To compensate: bass cut hard to 2 (original had no low-end), treble pushed to 8, and use the fuzz effect as your PRIMARY gain source. The slight reverb (2) adds the 'distant' quality of the original room sound. Rolling your PRS tone knob to 6 prevents the humbuckers from being too thick—Varg used thinner single-coil-ish Westone pickups.

PRO TIPFor true Filosofem authenticity, try running your guitar into a cheap home stereo aux input with a fuzz pedal in between, then mic the stereo speaker. The Catalyst will always sound 'too good'—embrace the lo-fi approach if you want the real frozen atmosphere.
