Broken reed? Buzzing reed? These are individual replacement reeds as used in Bina 23b and other Delhi style harmoniums. To ensure proper replacement, please determine the note and octave (i.e. B2, B3, B4...) you need and select that option. We will ensure that the reed you are replacing is the proper tone. In many cases, the size / length of the reed will be identical to the reed you are replacing. In other cases, there may be a slight variance and some minor adjustments may be needed for installation of the replacement reed.
