Playing tips
- Use your Metal Zone MT-2 distortion pedal to achieve the high-gain drive needed for the riff.
- Set your amp's reverb to a low level to add some depth without washing out the tightness of the riff.
- Engage the bright switch on your amp to enhance the treble frequencies for a sharper attack.
