当琴颈出现异常打品声时，可能是琴弦张力失衡的预警。专业乐手建议观察琴桥部位的锈斑程度，特别是青铜材质的民谣吉他弦更容易氧化。若发现按弦手指有明显阻滞感，说明镀层保护膜已开始脱落。
镍合金电吉他弦通常能维持25-35小时有效演奏时间，而古典吉他弦的尼龙芯需要特别注意湿度控制。实验数据显示，磷铜材质的贝斯弦在持续拨片弹奏下，音准稳定性比普通琴弦延长40%。
演出结束后用专用擦弦布清理指板油渍，能有效防止乌克丽丽弦的过早老化。存放乐器时建议使用干燥剂，特别是钢琴弦更要注意环境湿度。定期旋转弦钮调节张力平衡，可使民谣吉他弦保持最佳震动状态。
户外演出前建议更换全新琴弦组，避免温湿度突变导致琴颈变形。录制独奏专辑时，专业录音棚通常会准备多套不同规格的吉他弦备用。比赛现场的备用琴建议选择中等张力的镀膜琴弦，既能保证音色又不影响演奏手感。
