Sweet Child O' Mine
Guns N' Roses — Appetite for Destruction (1987)
Tuning: E-flat standard (Eb-Ab-Db-Gb-Bb-Eb)
Guitar: Les Paul-style guitar with humbuckers. Slash recorded Appetite for Destruction with a handmade 1959 Les Paul replica built by Kris Derrig; a bridge humbucker is a practical starting point for this recipe.
Playing: Fluid alternate-picked arpeggios, broad bends and expressive vibrato; use the wah as a vocal sweep in the lead solo.

JCM800-based Marshall model used here as a practical stand-in for Slash's modified Appetite-era Marshall.

Follow the chain from left to right. Optional blocks can be bypassed.
A thick, warm Marshall lead tone with a clear pick attack, strong upper mids and smooth sustain. The Les Paul humbuckers and amp provide the drive; avoid adding so much gain that the arpeggiated riff loses definition. Keep the wah bypassed for the main riff and use a broad, deliberate sweep for the lead solo. This chain covers the Marshall riff and lead sound, not the separate clean verse tone.
Tune every string down one semitone to E-flat standard. Start with Brit 2203 and 412 Brit 60B GB 90s, using a Les Paul-style guitar and bridge humbucker. Set the amp for a full, moderately saturated sound and adjust the mids until the riff stays clear. Add Crying Wah for the solo, but leave it bypassed for the riff. The amp and guitar should create the core tone; the wah supplies the main expressive effect.
Slash has said that he recorded Appetite for Destruction with a handmade 1959 Les Paul copy built by Kris Derrig. He also recalled that the solo tone on Sweet Child O' Mine came from a Marshall, while the clean verse chords used a Roland Jazz Chorus 120. Accounts of the Marshall used on Appetite differ: Slash has called it a JCM800, other research identifies a 1959 Super Lead or 1959T Tremolo, and Marshall has suggested a pre-JCM800 2203. The rental amp was modified for an extra gain stage, so no stock Quad Cortex amp is an exact match. Brit 2203 is based on a Marshall JCM800 and is the selected approximation for the hot-rodded Marshall character. Brit Plexi 100 Bright is another verified option if you prefer the Super Lead family as a starting point. Neither model recreates the missing modified rental amplifier. The 412 Brit 60B GB 90s cabinet is a practical Marshall-style cabinet choice; the exact cabinet and speaker combination for every track overdub is not established here. Slash's Derrig Les Paul is documented, but exact pickup selection and pickup position can vary across overdubs and are not confirmed for each part of this song. Begin on the bridge humbucker for a defined attack. Try the neck humbucker if you want a rounder, singing lead sound. Slash said he used a stock Cry Baby during the Appetite for Destruction period, and the song's lead solo is associated with a wah sound. Crying Wah is the Quad Cortex's verified Cry Baby GCB-95-based model. Its use and settings here are practical approximations, not recovered studio automation or pedal positions. Slash recalled using a Roland JC-120 for the clean verse chords. The Quad Cortex includes Rols Jazz CH120, based on that amplifier. That clean sound is intentionally not drawn in this serial lead chain. To cover the verse, build a separate clean preset using Rols Jazz CH120 and a suitable Roland-style cabinet model.
Tune to E-flat standard: Eb-Ab-Db-Gb-Bb-Eb, from the lowest string to the highest. This is one semitone below standard tuning and is needed to match the original recording's pitch and fret positions. A Les Paul-style guitar with humbuckers is the closest practical starting point to Slash's documented Appetite-era guitar. Use the bridge pickup first for the riff and a cutting lead sound. If the lead becomes too sharp, try the neck pickup or roll the guitar tone control down slightly. Keep the guitar volume and tone controls open while setting the initial amp sound. Use a moderate pick attack for the repeating arpeggios, then dig in for bends and sustained lead notes.
Build it in 5 steps
All numerical values are suggested starting points, not verified studio settings. Control ranges can differ between Quad Cortex devices. Set the amp and cabinet first, then add wah for the lead section. Match scene loudness when comparing settings.
Prepare the guitar
Tune to E-flat standard (Eb-Ab-Db-Gb-Bb-Eb). Start with a Les Paul-style guitar and bridge humbucker. Confirm that the strings remain in tune during wide bends, and set your guitar volume fully open while dialling in the amp.
Set the Marshall-style amplifier
Select Brit 2203. As approximate starting positions, try Gain around 5.5/10, Bass 4.5/10, Mid 6/10, Treble 5.5/10 and Presence 4.5/10, where those controls are available. Adjust the output or master level for the required volume. The source amp was modified and its exact settings are unknown, so use these values as starting points rather than historical facts.
Choose the cabinet and microphone
Select 412 Brit 60B GB 90s. If the cab block offers microphone choices, start with a dynamic microphone slightly off the speaker centre. If low and high cuts are available, try approximately 80 Hz and 8 kHz, then adjust by ear. Reduce the high cut if the tone is dull or move the microphone farther towards the cone edge if the top end is harsh.
Set the Cry Baby-style wah
Add Crying Wah before the amp. Leave it bypassed while setting the riff tone. For the lead, connect an expression pedal if available and sweep gradually through the range rather than parking at the toe position. If the effect sounds too nasal, reduce the sweep range or use less toe travel. These are practical adjustments, not verified settings of Slash's original stock Cry Baby.
Balance the lead level
Compare the riff and solo scenes at performance volume. If the lead needs to sit forward, raise its scene output by roughly 1 to 2 dB before adding more amp gain. Keep the notes defined and the bends vocal; excessive gain can blur the riff's string-to-string detail.
Set up your scenes
Main Riff
Use Brit 2203 and 412 Brit 60B GB 90s with the suggested starting settings. Bypass Crying Wah. Keep enough gain for a full, singing sound while preserving the articulation of the repeating arpeggios.
Wah Lead
Keep the same amp and cabinet. Engage Crying Wah and use a broad, expressive sweep for the solo. Raise the scene output by about 1 to 2 dB if the lead needs more presence. Add only a small amount of amp gain if extra sustain is needed.
The riff sounds muddy?
Reduce Bass slightly, check that the guitar is tuned to E-flat standard, and try the bridge humbucker. If needed, raise the cabinet low cut a little from its starting point.
The lead sounds too harsh?
Reduce Presence or Treble slightly, move the cabinet microphone farther from the speaker centre if available, or try the neck pickup for a rounder lead tone.
There is not enough sustain?
Raise Brit 2203 Gain gradually and check that the scene output is not too low. Increase gain only until the notes sustain through bends; preserve enough pick definition for the riff.
The wah sounds too pronounced?
Sweep through a smaller portion of the Crying Wah range and avoid holding it fully at the toe position. Bypass it for the main riff and engage it only for the lead part.
