www.jasonbecker.com I haven't seen his instructional video yet, it sounds great and is on my list.
One I have just bought is Brian Setzer's Hotlicks DVD which I happened upon in a music store. I'm still on the first exercise - although I've learned a lot of fingerstyle over the years I'm finding this quite demanding, maybe because it's years since I really applied myself to learning new tunes, or maybe because it doesn't have the 'simple repeating patterns' of the playing i'm used to, I have to take a lot more care jumping around the bass strings, but it'll click into place with practice.
The DVD is enjoyable in its own right just to hear Brian playing, there are several full songs played, and he looks like he had a fun time doing it. He does all the 'cool bigsby stuff' which I was hoping for - all I need now is a guitar with a whammy bar (could never afford a Gretsch, but maybe an Epiphone Wildkat some time..) to try that myself, and lots of cool runs up & down the fretboard. Oh, and I'm still supposed to be learning the Frank Gambale Monster Licks exercises, must get back to them too!
