Bass strings form the foundation of a piano’s rich, deep tone. Made of steel core wire wound with copper, they are prone to developing a “metallic rattle,” volume loss, or breakage over time, severely affecting playing experience. We offer professional bass string replacement for upright pianos, with custom-matched specifications by experienced technicians to ensure tonal consistency with the original design.

Services include: inspection of worn or broken bass strings, replacement with custom-spec wound strings, tuning pin stability check, and post-installation preliminary tuning with tension balancing.

Bass string replacement requires advanced craftsmanship. Special attention is given to smooth tonal transition when mixing new and old strings. Each string is custom-made according to the original piano’s specifications, ensuring tuning stability and tonal uniformity.

Suitable for bass sections with metallic noise, noticeably weaker volume compared to mid and treble sections, single or full-set corroded or broken bass strings, and deep restoration of used pianos.

A fine tuning is recommended 2 to 4 weeks after replacement to allow the new strings to fully settle.
