What can I play instead of Gadd9?
The nearest stand-ins on mandolin that keep the same root are Gsus4, Gsus2, G. They keep the root and the fifth and only change what sits in the middle, so most songs still work — but check the swap against the melody, because the note you removed may be the one the tune is singing.
