Playing tips
- Use your amp's built-in reverb set to a low level to replicate the spacious feel of the original tone.
- Dial in the distortion to achieve a saturated, aggressive sound suitable for chugging riffs.
- Keep the chorus effect off for this section to maintain the raw, punchy character of the riff.
