“An interview from June 2013 with Jorg Graf in Burnstown Ontario.” The folk over at Classical Guitar Training have a nice interview with Jorg Graf of Graf tuners. You can check out more videos by these guys at their YouTube channel.
I have to admit (with shame) that I did not know that Graf tuners were Canadian, I should have got them on my new guitar with is Canadian woods and luthier! Next time!
