I don't know how well known he is on the world stage, but there is a local guitarist who I think is amazing... John Butler.

I remember watching on in awe many times back when he was still street busking in Fremantle, Western Australia. The guy has serious talent and now passes on his knowledge to up and coming new artists through his production company.

Check him out on his beaten up old 11 string electric acoustic... one of his older tracks "Ocean" https://youtu.be/jdYJf_ybyVo
