Tobias Volkamer is a virtuosa German guitar and chromatic harmonica player. His playing both instruments simultaneously is just sensational. His videos have appeared on the Forum in the past. Back in 2010 he released a bunch of first class videos on YouTube but to my knowledge nothing has been heard of him since, which is a pity because he is an exceptional talent. He started on diatonic playing blues and rock I believe but he then branched out to Jazz etc.,
Does anyone have any idea of why he disappeared from the scene? Anyway if you haven't seen him before here are a few of his videos. As a rack player he had to devise a way of playing sharps/flats on his Chrome whilst playing his guitar so he hooked up a drum pedal to a cable to a lever to tap the slide button in as required!!
Guitar intro then rack harp on this Tommy Emanuel song.
Some amazing Bach
This video provides a closer view of the lever.
Here is his Hohner endorsee video in which he talks about his musical influences and his ingenious foot pedal cable which he uses to press the slide button.
