I toyed around with an acoustic guitar for some two years. Not really studying, but simply playing tunes, learning some chord positions and rhythm.
Last year I started taking lessons on the electric guitar and I love it. Though some three or four months ago Freelancer has stole my soul and my guitar practicing time was seriously impaired by my Freelancer playing. Anyway, I'm liking it better than the acoustic, I mean, bends, hammer ons, pull offs, it's just incredible what you can do. Not that I think one is actually better than the other, each has its place and purpose, but I amuse myself much more with the electric guitar.
