Israel "Iz" Kaʻanoʻi Kamakawiwoʻole

Brudda Iz used a regular high G Martin ukulele string set. This is how he achieved a low G tuning long before there were dedicated low G ukulele string sets available.

• For the G string four, Iz used the C string and tuned it low.
• For the C string three, Iz used the E string.
• For the E string two, Iz used the G string.
• Iz left the A, string one in the normal place.
