Product codes ending in "-1S" are Minor Blemished. They are New and Unused with Superficial blemishes that may include, slight blisters in the finish, minor scratches, dents, stains, discoloration, rust or pitting on metals, imperfect glazes, non-structural repairs such as putty in nail holes, or other surface marks. The irregularity does not affect the playability or sound quality of the instrument. These are a good value. Our Balalaika Prima measures approximately 27 inches in length. The scale length is 430 mm. The body has the classical triangular shape. The back is slightly bowed and made with stave construction in two tones of rosewood. The darker back contrasts with the light colored wood of the soundboard. The Balalaika strings are tuned above middle C to: A, E, E (1st-3rd). The 1st string is the thinnest, and lays over more frets than the 2nd & 3rd strings. Use a piano or electronic tuner as a reference for tuning. To play, the left hand notes the strings while the index finger of the right hand strums high on the soundboard near the neck. The dark rosewood on the soundboard is decorative but also protects the soundboard from the strumming. SPECIAL NOTE; No Warranty on Strings: Manufacturers recommend that you change the strings on your instrument as soon as you receive it. Your instrument has completed a long journey before it ever begins the final leg to your home. During this time the elements affect the strings and may shorten their lifespan. It occasionally happens that a string will fail during that final leg of the journey. Therefore, it is recommended that you purchase a replacement set of strings and consider changing your strings soon after it arrives. If you are a student you may want to change your strings every 3-4 months. If you are a rock star you may need to change your strings every week. If you store your instrument, you should consider changing the strings when you pick it up again. Featur
