From Master of Reality (1971). Master of Reality is the third studio album by the English heavy metal band Black Sabbath, released on 6 August 1971 by Vertigo Records. No source we found ties a guitar or amp to this recording, so a Gibson SG Standard through a Laney Supergroup LA100BL, the rig we use for Black Sabbath's other songs from Master of Reality, stands in. Set the amp to a medium-gain crunch and use the bridge pickup. Published transcriptions put it in a tuning that is not one of the standard names: C♯ F♯ B E G♯ C♯, low to high.
Common Questions About the "Embryo" Tone
What guitar did Black Sabbath use on "Embryo"?
The guitar on "Embryo" (released 1971) isn't documented; the Gibson SG Standard above gets the sound. Pickup selector: bridge pickup on the guitar. The track is in Custom tuning, so retune before you dial anything in.
What amp settings does "Embryo" need?
Settings for this sound: Gain 6.5, Bass 5.5, Mid 6.5, Treble 6.5, Presence 6, Volume 7. Each value is on the standard 0–10 amp scale; match them on your amp first, then nudge to taste. ToneMirror can translate these positions for whatever amp you actually own.
Can I play "Embryo" without the original gear?
Yes. ToneMirror takes the settings above and adapts it to your guitar, amp, and pedals - so you can chase the "Embryo" tone on a Katana, a Helix, a tube combo, or anything else. The translation accounts for EQ curve, gain structure, and pickup type so the result actually sounds like the record, not just the same knob numbers on different gear.
