Amp Designer
1x15 American combo · stand-in for an Ampeg V-92 with a blown JBL D-130
Auerbach told Guitar World the El Camino sessions ran through a Magnatone and an Ampeg V-92 with a partially blown JBL D-130, and that the JBL's death-rattle is what you hear introducing this track. Blues Blaster Combo matches the high-headroom American voicing and 1x15 cabinet better than any 2x12 silverface option, and pushing gain and master hard recreates the choked, broken-speaker character that defines the riff.

Finishing Touches
The riff lives on attack. Use a stiff pick, hit the strings near the bridge, and play with staccato authority. Loose right-hand dynamics turn the part to mush — this is a punchy, percussive performance.
Auerbach told Spin that almost every El Camino track has 'a foundation of live drums and guitar together in the room. It's guitar bleeding into the drum mics. It's pretty raw.' If you're recreating the full track, lean into a single committed take rather than stacking five surgical guitar layers.
Auerbach has said point-blank he's never used a distortion or overdrive pedal — only fuzz and boost. The dirt on Lonely Boy is the cranked amp plus the broken speaker. Resist the instinct to stack a Tube Screamer on top.
The signature 'wrong' sound is a damaged 15-inch speaker. To approximate it in Logic, lean on master and gain hard, accept that the amp will feel ugly in solo, and trust the mix context to make that ugliness sound right. Bitcrusher with a high cutoff at low intensity can also nudge things toward the broken character if you want to push it.
Notes
What's verified. Dan Auerbach told Guitar World in 2012 that the El Camino sessions ran through 'a Magnatone and an Ampeg V-92 with a JBL D-130 speaker' and that the JBL 'rattle' is audible 'at the beginning of Lonely Boy.' That quote anchors the amp choice and rules out the touring four-amp rig. In the same interview Auerbach stated he never used distortion or overdrive pedals on the record — only fuzz boxes and boost pedals — and confirmed a pitch shifter is the only effect on Lonely Boy. The 2014 Premier Guitar Rig Rundown corroborates by showing the live recreation uses a Boss PS-5 Super Shifter for that intro dive, and Wikipedia (citing primary sources) names the PS-5 directly.
Source disputes. Sources disagree on the guitar. Guitar.com's El Camino retrospective names a 1953 Gibson Les Paul as Auerbach's primary album electric. Equipboard, citing a 2022 Guitar World interview, attributes Lonely Boy specifically to Auerbach's 1954 Fender Stratocaster. The riff's bright, percussive, slightly stringy character reads as single-coil to my ear, so the card defaults to bridge single-coil. If you're playing humbuckers, roll back treble half a point and lean harder on the 2.5 kHz presence boost.
Logic Pro approximations. The Ampeg V-92 with a 1x15 JBL D-130 has no clean Logic equivalent. Blues Blaster Combo with the Brown Panel 1x15 cabinet captures the high-headroom American voicing and the 15-inch speaker character better than any silverface 2x12 option would. The blown-speaker rattle itself can't really be modeled — it's an artifact of the recording. Driving gain and master into hard breakup is the closest in-the-box approximation.
Things worth knowing. The bright keyboard countermelody is not guitar. Danger Mouse layered organ and Orchestron textures throughout the album, and the high-register hook line on Lonely Boy is one of them — many listeners assume it's a doubled guitar or synth. The track was cut at Easy Eye Sound in Nashville (spring 2011) on a 1969 Quad-8 console with drums and guitar tracked live in the same room. What sounds like a polished, tight mix is actually capturing deliberate room bleed — a defining part of the album's raw character. Danger Mouse produced with Auerbach and Carney co-producing.
Confidence summary. Amp and pedal are documented at song level from Tier 1 sources. Guitar choice is the only meaningful gap, and the dispute is between two Tier 2 sources interpreting Tier 1 interviews.
Sweet Child O' Mine
from Appetite for Destruction · Lead guitar — intro riff and solo
Signal Chain
Amp Designer
Late-60s 100W Plexi platform · Modded for extra preamp gain
Slash's Appetite amp was a Frank Levi-modded Marshall Model 1959 Super Lead — a non-master-volume Plexi platform with an added preamp stage, not a JCM800. The Vintage British Stack is Logic's closest model: Plexi-era voicing, smooth singing distortion, mid-forward but not scooped, with the headroom of a 100W head. Aim for liquid sustain rather than fizzy modern gain.

Channel EQ
Finishing Touches
Roll the guitar's neck-pickup tone control back to roughly 6–7 (out of 10) for the intro riff. This is the source of the 'vocal' character that no amount of EQ alone will recreate. Open it back up for the solo.
On the solo's high-register passages, Slash parked the Cry Baby in a fixed mid-travel position rather than sweeping it. The result is a steady nasal honk around 1.5–2 kHz. In Logic, leave the Classic Wah's pedal position static — do not automate it.
Add a Compressor on the FET (1176-style) circuit after Channel EQ with a 4:1 ratio, fast attack, medium release, 2–4 dB of gain reduction. This is the 'studio glue' you hear on the album — not pedal compression, just gentle leveling on the captured cab signal.
The album recording has a light plate-style reverb on the lead — not pronounced, but it's there. Add Space Designer with a Plate IR (medium plate), decay around 1.5 seconds, mix 8–12% wet. Resist anything bigger; the tone is closer to dry than to washy.
The single most common mistake is too much gain. Slash's modded Plexi sat around 5–6 on the gain control, not 9. The grit comes from a hot non-master-volume amp running its output stage, not from preamp distortion. If your tone is fizzy, pull gain back.
Izzy Stradlin's rhythm part runs through the same Marshall but a different guitar (often cited as a Gibson ES-175 or Telecaster on Appetite sessions). For that layer: open-position chords, less gain (around 4), no wah, bridge or middle pickup, panned opposite the lead.
Notes
What's verified. Producer Mike Clink confirmed in a June 2024 Total Guitar interview that Slash's amp on Appetite was the Frank Levi-modded Marshall Super Lead — SIR's 'Stock #36' — not the famous Tim Caswell-modded 'Stock #39' that Slash originally requested. Stock #39 had been rented to George Lynch for Dokken's tour. Both Slash (in multiple interviews) and engineering-history sources confirm the guitar was the Kris Derrig '59 Les Paul replica with Seymour Duncan Alnico II Pro pickups, brought to him by manager Alan Niven the night before overdubs after Slash's Jacksons and B.C. Rich sounded wrong in the room. The session ran at Rumbo Recorders, Canoga Park, August 1986 through early 1987.
Source disputes. Two questions get answered differently across sources. First, the amp: many older articles cite a JCM800, but this conflates Slash's live touring rig (which did include a JCM800 briefly, and then the Silver Jubilee from 1988 onward) with the studio amp. Clink's 2024 statement is the most authoritative — modded Super Lead, Plexi platform, not JCM800. Second, the intro pickup: most sources say neck humbucker with tone rolled back; a minority claim it's the bridge with tone rolled back. The neck-pickup reading dominates documented accounts and matches the audible character.
Inference reasoning. Knob values are inferred from Slash's general modded-Marshall settings as documented across interviews (gain 5–6, presence 6, slight mid scoop) and from what the recording sounds like, not from a specific Sweet Child source. EQ values follow Template A applied modestly — the Marshall is closed-back and distorted, but the gain level is moderate rather than modern-high, so the boxiness cut and presence boost are gentler than the template's full range.
Logic Pro approximations. Vintage British Stack models a stock Plexi, while Slash's amp was modded with an extra preamp stage giving it more gain than stock. Compensate by running gain slightly higher (6 rather than 4) than you'd use for a true vintage Plexi tone. Brown Stack and Modern British Stack are both wrong matches — Brown Stack is lower-voltage and looser, Modern British is JCM800-era with the deeper lows and brighter top that don't fit the 1987 recording.
Things worth knowing. The drum room ambience on the album is more pronounced than the guitar reverb — listeners sometimes attribute the song's spaciousness to guitar effects when it's actually the live drum sound bleeding through the mix.
