Tone Presets & Settings: Amplifier preset values are approximations of well-known recorded tones, derived from public community spreadsheets, interviews, and personal ear-matching. They are not factory presets, are not endorsed by any amplifier manufacturer, and individual results will vary based on guitar, pickups, room, and signal chain.
