From Your Favorite Toy (2026). No source documents the guitar or amp on this track, so a Gibson DG-335 (Dave Grohl Signature) into a Mesa Boogie Mark V stands in. Set a medium-high crunch on the bridge pickup and keep the low end tight. Tuning isn't documented here.

Can I play "If You Only Knew" without the original gear?
Yes. ToneMirror takes the settings above and adapts it to your guitar, amp, and pedals - so you can chase the "If You Only Knew" 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.
