Tom Morello’s Electro-Harmonix Small Stone Phase Shifter

Tom Morello used the Electro-Harmonix Small Stone phased on the song “Guerilla Radio” the effect can be heard during the “build-up” part just before the solo.

The phased sound before the solo is an Electro-Harmonix Small Stone. The solo is two tracks. On one part I’m using a Talk Box and triggering the notes with the toggle switch. The second part is the Whammy pedal set one octave up, with a wah and the toggle switch effect.

It’s interesting to point out that Tom has the MXR Phase 90 pedal on his pedalboard pretty much always, so it’s unclear why he decided to use the Small Stone phaser instead on that occasion. Maybe there’s some subtle thing that he liked about the Small Stone that the Phase 90 could not offer, or maybe the Small Stone was just the pedal that was around at that specific moment, so that’s why it was used.
