Playing tips
- Use your amp's built-in reverb set to a moderate level to recreate the spacious feel of the original tone.
- Engage the chorus effect to add a subtle shimmer to your sound, enhancing the jangly attack.
- Strum percussively but lightly to maintain an airy quality while allowing the open strings to ring.
