One by Metallica — Amp Settings & Guitar Tone
Reference tone dialed on a Squier Classic Vibe Stratocaster into a Fender Mustang LT25. Settings below are cited from real sources; open the page in a browser for the interactive version, or get this tone dialed for your exact gear.
To capture the dynamic tone of Metallica's 'One', we will use the Fender Mustang LT25 to emulate the Mesa/Boogie Mark IIC+ high-gain sound. The Squier Classic Vibe Stratocaster '60s will substitute for the ESP guitars used in the recording. We'll focus on achieving a scooped midrange with pronounced bass and treble, using the amp's built-in effects for delay and reverb.
Signal chain settings
Squier Classic Vibe Stratocaster '60s — Guitar for rhythm and lead
| Control | Setting | Why |
|---|---|---|
| Pickup Selector | Bridge Pickup | Select the Bridge Pickup for a bright and articulate tone, similar to the EMG 81 pickups used by Metallica. |
| Master Volume | 7 | Set to 7 to maintain clarity and dynamics in both clean and distorted sections. |
| Tone 1 | 10 | Tone wide open — roll it down to soften the high end. |
| Tone 2 | 6 | Dial to 6 to enhance the brightness and cut through the mix, emulating the scooped mids of the recording. |
Fender Mustang LT25 — Amp for rhythm and lead tones
| Control | Setting | Why |
|---|---|---|
| Preset | [14] THRASH OVERKILL | This preset is the best starting point for achieving the high-gain thrash metal tone of 'One'. |
| Gain | 8 | Set to 8 to achieve the saturated tube crunch in heavy sections. |
| Volume | 5 | Maintain at 5 for balanced output without overpowering the mix. |
| Treble | 7 | Increase to 7 to emphasize the bright and articulate character of the tone. |
| Bass | 6 | Set to 6 to support the scooped midrange and provide a solid low end. |
| Master | 6 | Output level — set to the volume you're playing at; this sets loudness, not tone. |
| Effects | Delay and Reverb | Engage delay and reverb to add depth and ambient space, matching the recording's subtle use of these effects. Using the amp's Menu Button and Preset Select, open the effects list to reach it. Start around Time 300-400 ms, Feedback 3/10, Level 4/10 — match the repeats to the song's tempo. Press Save Button to keep it in this preset. |
| Cabinet build | Not used | Not needed for this tone — leave it off. |
| Amp Models | Not used | Not needed for this tone — leave it off. |
