Power Flats are often not suitable for string-through-body basses or some 35-inch basses. Check your measurements before ordering.
Don't cut flatwounds to make them fit. Flatwound strings are generally less forgiving than roundwounds when cut.
Silencer semi-flats match the usable winding length of our long scale roundwound strings, so they fit many of the same instruments.
Measure your current string from the ball end to the taper and compare. If you're unsure, contact S.I.T. before ordering.
