I used to buy Guitar World and Guitar One from time to time. I liked Guitar World better, but I don't remember why. Then one day I realized that they're 60% ads and geared almost exclusively to people who are into the new hard-rock scene, which I am not. So I stopped buying.

I got a couple of those acoustic magazines (not Acoustic Guitar, the classier-lookin' ones) from my teacher once, but I couldn't really get into them either, not being too involved in the modern world of acoustic virtuosos.

I guess they're cool if you can find one that caters to your musical interests, but I never could.
