Description: A nine string guitar is any guitar having 9 strings instead of the commonly used 6 string guitar. The first type of 9-String Guitar, is often employed with three pairs of coursed strings similar to a twelve-string guitar. Often the three wound strings are single and the three thin strings are doubled to six strings. Some examples of this type of nine-string guitar are the Vox Mark IX and the Vox Phantom IX.
The second type of 9 String Guitar expands on the concepts of the seven and eight string guitar. When a lower string is added, the standard tuning becomes C# / F# / B / E / A / D / G / B / E. The scale length of 9 string guitars just as their six string counter parts. The scale is often lengthened for example; on the Ibanez RG9 / 712 mm / 28” inches instead of the common 25.5” inches. Tuning the highest string to an A4 or higher can be accomplished with a shorter scale length and or optionally a thinner string such as a .008 or .007 can be used.
