A set of 7 strings for the Russian guitar, manufactured for us by Daniel Mari Strings. The Tuning is as follows:

¶ = d',
· = b,
¸ = g,
¹ = D,
º = B,
» = G,
¼ = D'.
Tension is calculated to be approximately Medium to Medium High.
One word of caution: these strings are designed for a scale length of 650mm. If you have an 19th century Russian instrument,
chances are it has a much shorter scale length and using the La Bella strings might give you a low tension situation.
If all you do is playing solo, then there is no problem. Simply tune up the guitar by a semi tone or two.
But if you do accompaniments etc, that will not be good for you.
