Standard tuning on an 8-string guitar is F# B E A D G B E: six-string standard with a low B and a low F# added underneath.
What is 8-string standard tuning?
The top six strings match a regular guitar, the 7th string is a low B, and the 8th string is an F# a fourth below that. The lowest string sits around 46 Hz, close to the range of a bass guitar.
A popular variation is Drop E, which drops the 8th string a whole step from F# to E, an octave below a regular low E string.
