Angus Young Marshall Amp Settings
Angus Young's rig is defined by what it doesn't include. No pedals. No effects. No boost, no overdrive, no compressor. His entire signal path is: Gibson SG Standard → Marshall Super Lead 100W → 4×12 cabinet. The tone comes entirely from the amp at high volume, the SG's natural output, and his playing technique.
The Philosophy: All-Amp Tone
Angus's approach is the most direct possible. The Marshall Super Lead has a preamp that produces relatively little gain on its own — it was designed as a clean amplifier in the 1960s. Natural saturation comes from the power amp stage, which requires volume to reach saturation.
Running the Marshall at full volume (or close to it) saturates the output tubes and produces the characteristic Marshall "crunch" — a midrange-forward distortion with natural compression on the attack. This is fundamentally different from using a high-gain preamp channel or a distortion pedal, which produce saturation at lower volumes but with a different character.
Exact Settings
Marshall Super Lead 1959 (primary amp):
Volume: 10
Treble: 8
Middle: 7
Bass: 7
Presence: 7
SG settings:
- Bridge pickup
- Volume: 10 (full)
- Tone: 8–9 (very slightly rolled back to avoid harshness)
The SG's Contribution
The Gibson SG has a shorter neck (22 frets) and the neck joint at the 16th fret, which gives it a different resonance and sustain character to a Les Paul. The humbuckers produce a characteristically bright, aggressive tone with good midrange presence — ideal for cutting through a Marshall at high volume.
Angus uses the bridge pickup almost exclusively. The SG's bridge pickup is inherently brighter and more aggressive than a Les Paul's bridge pickup — the difference in guitar body and neck joint position contributes a different resonant character.
Replicating on Modern Marshalls
Marshall DSL40CR / DSL100H
The DSL's Classic Gain channel (not Ultra Gain) is the closest to the Plexi character. Set Gain at 6, Volume at 6, Treble 8, Middle 7, Bass 6, Presence 7. The DSL's preamp adds more gain than a Plexi, so Gain should be kept lower to approximate the power amp saturation character.
Marshall JVM410H
Channel 1 Crunch mode. Gain at 5, Master at 5, Treble 8, Middle 7, Bass 5, Presence 7. JVM Channel 1 Crunch most closely approximates the Plexi's natural saturation.
Marshall Origin 20H
Designed to capture Plexi tone. Volume at 8, Tone at 6, Treble at 7 (the three-control EQ). Add the tilt switch for more treble presence. This is one of the most accessible modern Marshalls for the AC/DC tone.
Marshall SV20H
The closest modern Marshall to the Plexi circuit. Pull the Volume knob to drop to 5W, then run at Volume 8. Treble 8, Middle 7, Bass 6, Presence 7.
Replicating on Modellers
Line 6 Helix / Pod Go
Amp: Brit Plexi Bright (1959 Plexi model)
Drive: 5.5, Bass 5.5, Mid 6, Treble 7.5, Presence 6.5, Master 7
No effects chain — clean signal to amp, nothing else.
Fractal Axe-FX III / FM9
Amp: Plexi 100W Hi
Drive: 45%, Bass 5, Mid 6, Treble 7.5, Presence 6.5, Master 7.5
Cabinet and Speaker
Angus uses Marshall 4×12 cabinets with Celestion G12T-75 or Vintage 30 speakers. The G12T-75 is standard on most production Marshall cabs and suits the AC/DC tone well — tight, forward, with the presence peak around 3kHz that gives the SG its characteristic cut.
The Elevator Pick Technique
Angus's distinctive rhythm technique — extremely consistent downstroke picking with a controlled pick angle — produces a tighter, more aggressive attack than alternate picking. This technique contributes significantly to the characteristic "crunch" of AC/DC rhythm guitar.
The amp settings alone will not produce the AC/DC sound — the consistent, physically demanding downstroke rhythm technique is essential and distinguishes authentic imitation from superficial approximation.
Why Zero Pedals Is the Actual Recipe, Not a Missing Ingredient
Most players assume a rig this simple must be missing something — surely there's a boost, a slight overdrive, something. There genuinely isn't. The entire tonal complexity of AC/DC's guitar sound comes from exactly three variables: the SG's bridge pickup output, the Marshall's power-amp saturation at real volume, and Angus's picking technique. This is worth taking seriously as a design principle rather than a curiosity — every additional component in a signal chain is an opportunity to move away from a target tone, not just an opportunity to add character. Angus's rig is the clearest possible demonstration of that principle on this entire site.
The practical lesson: chasing this tone by adding "just a little" boost or overdrive to compensate for an underpowered amp setup moves further from the target, not closer. The fix for insufficient saturation is more amp, not a pedal standing in for amp volume.
Common Mistakes
Adding any overdrive or boost pedal "to help." As explained above, this is the single most common mistake players make chasing this tone — the entire point of the rig is that saturation comes from the power amp stage at real volume, and a pedal produces a different, distinguishable character even at a light setting.
Using alternate picking instead of committed downstrokes. As the "Elevator Pick Technique" section states, the amp settings alone don't produce the AC/DC sound — the physically demanding, extremely consistent downstroke technique is doing real work that alternate picking simply doesn't replicate, regardless of how accurate the gear is.
Choosing a Les Paul instead of an SG for this tone. As the SG's contribution section explains, the SG's lighter mahogany body, shorter neck, and different neck-joint position produce a genuinely brighter, more aggressive resonance than a Les Paul — the guitar body type is a real variable, not an interchangeable detail.
Assuming any high-gain modern amp channel replicates power-amp saturation. As the replicating section notes, a preamp-driven gain channel (like a DSL's Ultra Gain) produces distortion at low volume through a different mechanism than genuine power-tube saturation — the Classic Gain channel, run harder, is the more accurate target even though it offers less raw gain on paper.
ToneStakr's Take
For players building this rig, resist every instinct to add a pedal — a Gibson SG Standard's bridge pickup straight into a Marshall-style amp genuinely driven hard (not just EQ'd aggressively at low volume) is the complete formula. Budget real practice time for the downstroke picking technique; without it, even a period-correct SG-into-Marshall setup will sound noticeably less tight and aggressive than the genuine article.
Frequently Asked Questions
What model SG does Angus use?
A standard Gibson SG Standard with stock humbuckers (PAF-style character). His current signature model includes Angus Young-specific pickups, but any genuine SG Standard gets you into the right tonal territory.
Which Marshall does Angus use?
The 1959SLP Super Lead 100W, with all controls set between 7 and 10 — the entire rig is amp gain only, with no pedals of any kind in the signal path.
Can I get the AC/DC tone with a Marshall DSL or JCM800?
Yes, reasonably — turn up the preamp and master volume until the amp naturally saturates rather than relying on a distortion pedal. Angus's tone is fundamentally power-amp saturation, which requires genuine volume to replicate, not just gain-knob position.
What makes his rhythm tone so distinctive?
The combination of the SG's naturally bright, aggressive bridge pickup and the Marshall's midrange-forward saturation, driven by his "elevator picking" technique — extremely consistent, physically demanding downstrokes that produce a tighter, more percussive attack than alternate picking.
Is it possible to get this tone at home without genuinely loud volume?
Only partially — a quality amp modeller with an accurate Plexi-style model captures more of the power-amp saturation character at low listening volume than a real tube amp turned down ever will, since a real amp's saturation is physically tied to its actual output level in a way modelling can bypass.
Does the cabinet matter for this tone, or is it mostly the head?
It matters genuinely — Angus's Marshall 4x12 cabinets loaded with Celestion G12T-75 or Vintage 30 speakers contribute a presence peak around 3kHz that's part of the SG's characteristic cut through a mix, not just an incidental detail of whichever cabinet happened to be available.
