Playing Technique

• 🎸Alternate-pick the pulse evenly · difficulty 4/5Use small down-up strokes and make the open-string notes match the fretted notes in volume. Relying only on hammer-ons and pull-offs often makes the accents uneven and weakens the mechanical drive.
• 🎸Keep the fretting hand close · difficulty 4/5Lift each finger only far enough to clear the string, then return immediately. Large motions create timing gaps at speed and make the clean tone expose every late arrival.
• 🎸Mute both neighboring strings · difficulty 4/5Let the fretting finger touch the string above while the picking hand controls the string below. The riff sounds huge because one string is precise; accidental ringing makes it feel unfocused.
• 🎸Build endurance before speed · difficulty 5/5Practice short, perfectly even bursts and extend them gradually. Tension in the thumb or forearm will compress the attack and push the riff ahead of the beat long before the song reaches full length.

Tone Story / Why This Tone Works

• ⚡Style and eraThunderstruck launched AC/DC's 1990 The Razors Edge era and helped restore the band's hard-rock scale after a quieter late-1980s stretch.
• 🎸Angus Young's signatureAngus developed the opening figure from a warm-up idea; Malcolm then helped shape the arrangement around its bright, relentless pulse.
• 🔍Why the riff stays cleanLow gain and a dry response keep the open-string pulse separate from the fretted notes. More saturation would make the figure sound smaller, not bigger.
• 🏟️Why it becomes an anthemThe repeated lead line builds tension before the band enters, then remains audible as the track's signature signal above the full rhythm section.
