3.2 Initial Tuning
A 12-string guitar requires careful tuning due to the doubled strings. Use the provided clip-on digital tuner or the guitar's built-in tuner for accuracy. The lower four courses are typically tuned in octaves, and the upper two in unison. New strings may stretch and require frequent re-tuning initially.

3.3 Truss Rod Adjustment
The guitar is equipped with an adjustable truss rod to maintain neck straightness and optimize action. If you experience fret buzz or find the action too high/low, minor adjustments may be necessary. Use the included Allen wrench for this purpose. It is recommended to make small, incremental adjustments and allow the neck to settle before further changes. If unsure, consult a professional guitar technician.
