From Bodies (2025). Bodies is the third studio album by Australian alternative metal band Thornhill. No source we found ties a guitar or amp to this recording, so an Ibanez RG Iron Label RGIB21 Baritone through a Kemper Profiler Rack, the nearest rig we use for Thornhill's other songs, stands in. Set the amp to a driven, high-gain crunch and use the bridge pickup.
Common Questions About the "Under the Knife" Tone
What guitar did Thornhill use on "Under the Knife"?
The guitar on "Under the Knife" (released 2025) isn't documented; the Ibanez RG Iron Label RGIB21 Baritone above gets the sound. Pickup selector: bridge pickup on the guitar.

Settings for this sound: Gain 7, Bass 6.5, Mid 5.5, Treble 6, Presence 5.5, Volume 6. 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 "Under the Knife" without the original gear?
Yes. ToneMirror takes the settings above and adapts it to your guitar, amp, and pedals - so you can chase the "Under the Knife" 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.
