Playing tips
- Use your amp's built-in delay set to a moderate level to recreate the rhythmic repeats of the original tone.
- Engage the chorus effect for a swirling modulation that enhances the riff's texture.
- Maintain a tight palm muting technique to achieve the percussive attack characteristic of the original riff.
