Iorn man amp settings — Roland Cube 40GX

The Black sabbath guitar tone for “Iorn man”, dialed in for a Roland Cube 40GX with a Harmony Stratocaster. Studio version, Paranoid (1970) — the iconic slow, doomy riff recording

Original rig

Laney Supergroup 100 head, Gibson SG Special with P90-style pickups, no pedals — amp cranked for natural tube saturation, guitar tuned down 1.5 steps to C#

Thick, grinding mid-focused crunch with murky low-end and smooth, rounded highs — not buzzy or modern, more like a woolly growl

Why these settings

Your Cube 40GX's LEAD model is solid-state and brighter than Iommi's cranked Laney tubes, so I've pushed mids to 8 and cut treble to 4 to avoid fizz and capture that woolly midrange bark. Your Harmony Strat's single coils are thinner than his SG humbuckers — the rolled-back tone knob (6) and boosted bass (7) compensate for the output and frequency difference. Reverb at 0 because the original is bone dry.

PRO TIPIommi tuned down to C# standard — if you can't detune that far, try Drop D at minimum and play the riff starting on the 5th fret of the low string instead of open; the slack string tension is half the tone's weight.
