Jack Repair
Jack repair refers to fixing the input/output connection points on musical instruments, particularly electric guitars, basses, and other electronic instruments. These jacks are where musicians plug in their cables to connect instruments to amplifiers or recording equipment. When these connection points become loose, worn, or damaged, they need specialized repair to ensure proper sound transmission. This is a common repair skill needed in music stores, repair shops, and custom instrument workshops.
