About Tom Morello's Sound

Thomas Baptist Morello (born 1964) redefined what the electric guitar could do in Rage Against the Machine. A Harvard political science graduate, Morello created DJ-like scratching, turntable effects, and electronic sounds using only a guitar, amp, and pedals - no samples. His arsenal of unconventional techniques (using the toggle switch, rubbing cables against pickups, feedback manipulation) influenced hip-hop producers and guitarists alike. After RATM, he co-founded Audioslave and Prophets of Rage. A vocal activist, Morello has used music as political protest throughout his career.

Why Tom Morello uses these

Morello's famous 'Arm the Homeless' guitar (a custom parts Stratocaster) and his signature 'Soul Power' Telecaster are both set up with standard .010-.046 strings in Drop D. His innovations come from technique and pedals, not specialized setups. The Digitech Whammy pedal is essential to his sound, creating synth-like pitch shifts. Morello's approach proves that radical sounds can come from conventional equipment used unconventionally. His killswitch (toggle switch) technique creates rhythmic stuttering effects. The story goes that 'Killing in the Name''s riff was invented while teaching a student Drop D tuning.
