I too used to subscribe to and read Guitar World when starting out, but it ran out one year and I didn't miss it, so I haven't read one since. But then I got a subscription to Guitar One as a Christmas present a couple of years ago, and that was cool. I remember the lessons being what I usually liked most. But again, it ran out and I didn't bother with it.

My favorite "mag" is prolly just a good ole Musician's Friend catalog. :p
