French guy, will be in Hawaii in august 2009.
I'll be visiting Oahu, Maui and Kauai.
Can you advice me guitar shops there ?

Thank you

There may be folks around this forum, but not many folk musicians.

Check the Acoustic and Classical Guitar section.

The best advice I can give you is that a Geiger Counter is amazing for Electric Acoustic Folk Guitar.
