Phase-Cancelled Laney Snarl — Fixed-Wah Riff
The signature riff was recorded fingerstyle with a Gibson Les Paul through a Laney amplifier, with a wah parked in a fixed position to emphasize the nasal midrange. Sources disagree over the precise Les Paul model, while the strange texture also depended on two microphones combining partially out of phase, so the settings are representative rather than an exact knob sheet.
