保持音调稳定的优质变调夹
GREG OLWELL撰稿

 

全新的G7th传承变调夹是一款优质变调夹,采用由来已久的轭式设计,加上G7th独创的橡胶垫横梁,让我在试弹数把吉他的时候几乎不用重新调音。

 

首先了解下变调夹的背景故事:这种重要的辅助工具已经存在上百年了,所以就收回那些讽刺变调夹是“不中用”的鬼话吧。虽说变调夹的原理十分简单,不过其外观设计有上百种。多数乐手都很熟悉这种夹在琴颈一侧,使用弹簧、螺丝或杠杆原理夹在琴弦和琴颈上的工具,就像是龙虾钳。轭式设计的应用可追溯到18世纪,夹在琴颈,然后通过一个尾部滚轮和橡胶垫横梁向变调夹均匀施力。此款传承变调夹采用抛光不锈钢打造,光面版
(评测型号)或雕花款(叶形雕花或定制签名)均有销售。变调夹横梁上的橡胶垫可拆卸更换,被G7th称为“曲率半径自适应技术”。这也是传承变调夹的关键,即一个小小的机械凸轮,帮助橡胶垫适应指板曲率半径,均匀地将将琴弦下压,同时吉他不会跑调。

 

我在众多琴颈不同的吉他上试用了这款传承变调夹,有的带有扁平的传统指板,有的为复古琴颈,还有Martin移动顺畅的琴颈。结果发现,在夹上变调夹后完全不需要重新调音。只需轻轻夹上变调夹就可转调(不要过紧或过松),然后开始弹奏即可。

 

高端变调夹市场的竞争十分激烈。这款G7th传承变调夹外观精美,制作精良,满足专业乐手着眼于稳定调音与高品质的需求。
