He may have been having fun @ my expense, but Curly Chalker once told me to pick a pro player & copy everything they ever did on recordings....his thinking was that Id then have a vocabulary of chops & would've(hopefully), by that time, learned where things are on the guitar & how to think. Then he said to pick another player & repeat the process, etc.....He also intimated that, along with lessons from the local hawiian guitar teacher when young,this was how he, Buddy, Hal, Weldon, etc had done it; the heroes of his younger days being Jerry Byrd, Speedy West, Little Roy Wiggins & of course, Joaquin Murphey.
A lot of early days & late nights at the turntable & guitar resulted from his advice...lotta good gigs too! Thanx, Curls

This of course, was before the days of seminars, courses, forums,etc.
With the material available now
from so many sources, one should, with the proper motivation & practice, be able to learn at a much accelerated pace, as compared to before.
However, nothing can compare to having a good teacher to put you on the right track. Seeing & hearing it happen right in front of you is imho,invaluable.
