From Terminal Velocity (2020). Terminal Velocity is the second studio album by Dream Theater guitarist John Petrucci, released digitally on August 28, 2020 and on October 30, 2020 for the physical version (vinyl and CD). It is a new version of a song Petrucci used to play live on the G3 tour. No source we found ties a guitar or amp to this recording, so a Music Man John Petrucci Majesty through a Mesa Boogie Mark IIA, the rig we use for John Petrucci's other songs from Terminal Velocity, stands in. Set the amp to a driven, high-gain crunch and use the bridge pickup. Published transcriptions put it in D standard (D G C F A D), a whole step below standard.

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