I have been mostly working with fingerpicking on my acoustic guitars. I use a pick for strumming but never have been able to pick out single notes quickly with a pick.
On Wednesday I was jamming with those five other guitar players and the mandolin, and I was strumming away, and then.. I started playing single notes with a pick. Arpeggios. This is a big step for me. I can actually do single note picking ok if i'm moving laterally along the neck, but moving from the low E to the high E has just stumped me. But there I was, doing it. I about squealed. It wasn't particularly precise, but the arpeggios were recognizable. So I'm pretty thrilled about that.
