I’m new here and this is my first post.
My advice is: Don’t give up hope. I can remember complaining to my wife that I would never be able to play those fiddle tunes up to speed. But, low and behold, it all started to come together in time. Proper right hand technique is the key. I worked for two months constantly to break 20 years of bad technique in my right hand. It’s much better, but still not perfect. Look at Ben’s technique and try to emulate it. Keep loose - rigidity in your right hand kills speed. Pick from your wrist, and not your elbow. (OK, I know that Bill Monroe didn’t and Ricky Skaggs doesn’t, but in general, this is true). At the intermediate level and above, a Blue Chip pick will add about 10% or more to your speed. It just slips through the strings better than a cheap pick. Practice with a metronome. I had an old Zoom digital recorder that you could program rhythm tracks into and then play back at variable speeds without changing the pitch. I worked with this for several months and it improved my speed greatly. Try to find jamming partners that are a little more (or a lot more) advanced than you are, so you feel challenged to improve. And most of all: Practice, Practice, Practice. Keep the faith. It will come together. OrrinJ
