Ninety five per cent (95%) of all individual bass strings can be replaced with our Universal Strings listed below.
All of the universal strings have only one layer of copper. These strings can be used for temporary replacements while custom made strings are being made.
If your piano is very old, and has black or grey colored iron windings, it's advisable when ordering a "Unison String" or "Bi-Chord String" (more than one string to the note), to order both of them, so you will have an even sound.

Measurements shown in the diagram above:
1) - Length from the Hitch Pin to the Winding
2) - Length of the winding.
3) - Micrometer measurement of the outer copper wound diameter (in 1000th of an inch)

The following bass strings are for individual replacements. You need only to unwrap any excess copper and cut to the desired size.
Use the adjacent string as a measuring guide. 

NOTE: ...Please measure carefully before ordering - Due to the sensitivity of handling copper winding, Bass strings are NON returnable.
