I got a decent acoustic ibanez about 1.5 years ago and it's really spurred me to actually learn how to play. I don't know a lot yet but I really enjoy just jamming around a key for 1 or 20 minutes here or there.
There is something viscerally enjoyable about coaxing what seems to be coherent language out of an instrument and recognizing it as coherent even though I can't actually put me finger on what it's saying, at least not in words.
The whole pentatonic scale is kind of weird, it just seems like each note really makes sense in relation to each other.
I think I need a beer.
