Great to hear from you and good to know that you found my comments about hybrid picking interesting. I shall try to tell you want I think about it.
I got really interested in hybrid picking around 2007 after a got myself a lovely telecaster. After watching too much YouTube and wanting to learn old school early 50s rock and roll. The YouTube algorithms then also brought up some videos where I discovered chicken picking, James Burton, Brent Mason and Albert Lee. I got really interested in learning to hybrid pick on electric guitar and I quickly realized that you could use this hybrid picking technique to play lots of the Travis picked tunes that I already knew.
With hybrid picking alternating the bass notes with a regular pick instead of your thumb is pretty straight forward - though it does take some time to adjust. The only downside is that your index finger (which is supporting the pick between the thumb) becomes redundant when picking the melody notes. I used to use my index finger as one of the fingers to play the melody when I first learnt pick in the traditional style. I now play the melody with the middle and ring fingers only. I do sometimes use my little finger, but mostly on electric as you simply don’t get enough articulation on an acoustic with your little finger.
I do also still sometimes Travis Pick traditionally with my thumb - as you never seem to forget how - but my index finger just hovers above the strings - not sure what to do with itself now it is not needed to support the pick. I can still use it to play the melody, but my ring and middle finger timing gets quite confused if I do as they are so used to doing all the melody work now. There are some vamps and rolls that you learn to do without too much thought (if you practice a lot) - My index finger just isn’t up to it anymore - though I could probably teach it.
I shall try to sum up what I think about the various approaches.
Traditional Travis picking with a thumb pick gives the greatest punch to the bass notes. It is the sound that was originally heard and if you are trying to accurately replicate a Doc Watson, Merle Travis or Chet Atkins style then this is what you need to learn.
Hybrid picking with a pick is smoother and faster. It is very comfortable and easy to do - you don’t have to move your hand or fingers as much - so its quite economical. It also seems to offer some technical advantages for ways of playing that you couldn’t easily do with Travis style. It’s much easier to move a regular pick through any of the strings (not just the bass notes) than weave a thumb pick in an out of all six strings. There is also plenty of scope for experimentation and cross over electric guitar techniques. The biggest downside for hybrid picking is that I think it lacks some the attack to the bass notes of the traditional style. It works brilliantly on an electric guitar and you can play some incredible Travis style stuff. I’d say that it’s a bit smoother and mellower than the traditional Travis style on acoustic. You can also transition from Travis picking to straight flat picking without missing a beat.
Finally, when I first began to hybrid pick on acoustic not many people seemed to be doing it. I’m pretty sure that quite a few younger players out there are doing this now because it’s a more well known technique. We’ll probably all witness an amazingly gifted young hybrid acoustic player who will astound us all with their modern and original interpretations of the Travis picking style come out sometime in the future. Who knows?
All the best and whatever approach you use, keep practicing!
