How to get any song's guitar tone on the amp you own

Step 1: Find the documented rig

Start from what the player, the producer or the engineer said was used on that recording, in an interview or a studio account. Gear lists on fan sites often show a touring rig from years later. Master of Puppets is a good example: James Hetfield's ESP guitars came after the album, which he recorded on a Jackson King V through a Mesa/Boogie Mark IIC+ used as a preamp into Marshall heads.

When sources disagree, keep both and look at what they share. Slash has called the amp on Sweet Child O' Mine a JCM800, while Marshall believes it was an earlier model. Either way it was a 100-watt Marshall modified for extra gain, and that is the part that decides your settings.

Step 2: Pick the part you are after

Many songs have more than one guitar sound. Smells Like Teen Spirit puts a chorus pedal on the quiet parts and a Boss DS-1 on the loud ones, and In Bloom's verses and choruses went through different amps. Decide which part you want, rhythm or solo, clean or driven, and set each one up as its own sound.

Step 3: Match the amp family, not the model

Amps fall into a few families with recognisable voices: Fender cleans (Twin, Deluxe, Bassman), British crunch (Marshall Super Lead, JCM800), Vox chime (AC30), American high gain (Mesa/Boogie Mark and Rectifier), and solid-state heads, such as the Randall behind Cowboys from Hell. Work out which family the original belongs to and choose your closest channel or model.

On a modelling amp that choice is the amp model, and it matters more than any knob: on a Boss Katana the Clean, Crunch, Lead and Brown types set the gain structure before the Gain knob does. On a two-channel valve amp it is the channel. On a single-channel amp it is the pedal you put in front.

Step 4: Set the gain lower than you think

Recorded guitars sound more distorted than they are. Heavy parts are usually several takes layered, and studio compression evens them out, which reads as extra gain. Start with the gain below where you think it goes and raise it until a riff from the song holds together, then stop.

The Cranberries' Zombie is a good test of this. Its weight comes from three guitars layered through cranked AC30s and Marshalls, so one guitar with the gain maxed turns to fizz instead of getting closer.

Step 5: EQ against the record at the same loudness

Play along with the track, with your guitar about as loud as the guitar on the record. A louder sound always seems better, so matching the level is what keeps the comparison honest. Start with every EQ knob at 5 and move one at a time: is the record brighter or darker than you, fuller or thinner in the middle?

The middle is usually where the answer is. Rock and blues records are mid-forward; the scooped sound belongs mostly to thrash and some metal. Cut the band that sounds wrong before you boost another.

Step 6: Use the same pickup

The pickup position changes the tone more than most EQ moves, and some parts are documented. Eruption is all bridge pickup, because the Frankenstrat had only one. The rhythm of Little Wing sits between the neck and middle pickups, and Mark Knopfler has said Sultans of Swing is his Strat's switch jammed between two positions. With no source, the bridge for driven rhythm and the neck for a warm lead is the safe default.

If your guitar has different pickups from the original, change the gain rather than the EQ. Humbuckers push an amp harder than single coils, so take the gain down a step with humbuckers and up a step with single coils.

Step 7: Add only the effect the song is built on

Most songs need nothing beyond a little reverb. A few are built on one effect: the Seven Nation Army riff is a Whammy set an octave down, Come As You Are is a Small Clone chorus, and the Comfortably Numb solos are a Dyna Comp and a Big Muff into a Hiwatt. Add that pedal, in the right place in the chain, and leave the rest of the board off.

Worked example: Master of Puppets on a Boss Katana-50 MkII

The rig: a Jackson King V through a Mesa/Boogie Mark IIC+ used as a preamp, into Marshall heads and 4x12 cabinets. That is American high gain feeding British power amps, with the tight, scooped palm-muting the album is known for.

On the Katana: the Lead or Brown amp type (try both), Gain 6 to 7, Bass 5 to 6, Middle 3 to 4, Treble 6 to 7, Reverb at 1 or off, and the bridge pickup. The Middle goes lower here than this site usually suggests because the record is scooped, but below 3 fast downpicking loses its definition. The Katana-50 MkII has no Presence knob, so the top end comes from the Treble alone.

If palm mutes blur, lower the Gain a step and switch in the Booster's Mid Boost, which sits in bank B on a MkII as shipped. Then check against the record at the same loudness and move one knob at a time. It will still sound smaller than the album, which is a mix of layered takes, microphones and mastering. That is expected, and more gain does not fix it.

Doing it for every song

The method is the same for any song; the work is in steps 1 and 3, finding a rig you can trust and translating it to a panel that is not the original. Tonelify does that translation: it reads the documented chain behind a recording and returns positions for the amp and guitar you own, using only the controls on that amp.
