Mark, I am not sure it was a terrific thread before your post, but it was after--anyway, what is the thumbed D pattern, string by string? I have a pretty good idea what you mean, but I want to be sure--

Flattop--sad but true that people need this basic guitar technique stuff--I have said it before, and I'll say it again--when you try to teach yourself to play guitar, you miss an aweful lot--

If you play guitar, and Flattop's clear, concise, and helpful post was a revelation to you, then a warning bell should sound--you need to sit down with someone whe is a good guitar teacher--not to learn some note for note of a Blind Blake tune, but to fill in the gaps of your basic technique--
