Richard,
Nice sound, and you are correct on the old pull-release steels.
I still have to get mine back together, and I'll let you hear another, however a G.E.S. After the years of playing it, I simply can't get the same results out of these newer steels.
Then too, maybe it's my bad playing that's doing it from too much time off. Struggling to make a comeback for my own use this time around. And to date, it's sure not all that good.
I'm down to only being able to use my left leg for the knees, only until after surgery, hopefully!
Nice job
