- What separates stoner from sludge?
- Temperature and mood. Stoner is warm, round and blues-inflected with melodic vocals and a relaxed feel. Sludge is filthy, clogged and carries hardcore rage with shouted vocals. Both are slow and heavy; one rolls, the other grinds its teeth.
- How do I get that old-amp tone?
- Prompt for a fuzz pedal into a valve amp, warm saturated tone with hair on it, tape saturation, and round rather than tight low end. Warm and saturated are the operative words; asking for high gain or tight pushes you into modern metal and loses the period character.
- Why does my result feel rushed?
- Systems default to a tight grid for anything called metal. Specify 70–95 BPM, drums laying back slightly, space between riff statements, and no double kick. The swing comes from the gaps and from hits landing a touch behind the beat.
