Russian guitar
The Russian guitar (sometimes referred to as a "Gypsy guitar") is an acoustic seven-string guitar that was developed in Russia toward the end of the 18th century: it shares most of its organological features with the Spanish guitar, although some historians insist on English guitar descent. It is known in Russian as the semistrunnaya gitara (семиструнная гитара), or affectionately as the semistrunka (семиструнка), which translates to "seven-stringer".
