8 String Guitar Tuning Guide
Interested in an 8-string guitar? We’ll explain how it’s tuned.
What Is the Standard Tuning on an 8-string Guitar?
An 8-string guitar is like a regular 6-string, but with two lower strings for playing notes in the bass register.
Standard tuning on a 6-string guitar is E A D G B E, from the sixth string, the lowest in pitch, to the first string, the highest.
The 8-string adds a seventh string tuned to the musical interval of a fourth lower, which is B. The eighth string is tuned another fourth below that, at F#.
Standard tuning on an 8-string guitar is therefore F# B E A D G B E.
However, guitarists in your favorite bands may use one of many alternate tunings.
Changing Strings on an 8-string Guitar
Changing strings on an 8-string is the same procedure as on a 6-string guitar. However, you need to take care to select the right set of strings with the correct gauge for each string.
An 8-string is an extended-range guitar: the strings are longer than those on a regular guitar. Eight-string guitars are intermediate in scale length between the shorter 6-string guitar and the longer bass guitar.
The set of strings you need will depend on the scale length of your 8-string, which can vary between 27 inches (686mm) and 29.5 inches (750mm) and whether or not your guitar has a single scale or is multi-scale (the design where each string has a different scale length).
When in doubt, go to your guitar manufacturer’s website, find the listing for your model, and look at the specifications to find the string gauges. Buy a new set with the same gauges.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
