I'm a reasonably accomplished guitar player, having played professionally and semi-pro for the better part of 30 years, but am now interested in expanding my horizons a bit. I've always loved the pedal steel sound and, for the first time in forever, have the time to pursue a new instrument. My knowledge about these is pretty much zip, so please school me. How hard is it to learn? How much should I spend on a beginner instrument? What are some good learning resources? YT videos, online instruction, etc.?
