Johnny - do you mean that Scruggs style requires a five string banjo to do it? If so, why exactly? Remember that a guitar has six strings and nobody MUST play them all at once.
Mark - is what you call a 'flat pick' really that single piece of a credit card I think I understand it to be? If so: Can you tell me more about it? If not: What is a flet pick? (I simply can't imagine how to do anything like Scruggs style with a single pick.)
To you all - please try to understand that certain things that seem obvious to you are unknown to me. That's why I had to ask Spaw in 'fret fret fret' what Lysol is. I am also a guitar player knowing few about banjos although I am doing nothing but fingerpicking and also once tried that with a six string banjo (wholesome experience).
Moreover I am living in a region where people slowly begin to accept country music - provided it's performed in german by some tired-looking guy singing lower than his voice really is (arghh!). Do not think that I can get any support for things as specific as 'bluegrass' here. This has become better during the last decades but still there are hardly any more serious resources for me than YOU.
I still think that there should be a way to do something like Scruggs style on the guitar but I never found out how the right hand works. I can't hear it because I am a really bad listener (to musical details!) and it simply goes too fast. But maybe it's only for the fifth string. Is the left hand involved? I don't know, but I am VERY interested. It IS possible to work melodies into arpeggios - I am doing it but not that way.
