I agree--Premier Guitar is the best US guitar mag out there right now. I've been reading Guitar Player since the first issue back in '67 (jeez, I'm getting old!), and while they've been better, they've also been worse--they do have to try to be all things to all players in order to maintain market share. Seems like the young guys complain because they're covering old farts, and the old guys complain because they're covering young punks. Still a good magazine, though. I remember back in the first year of publication, some old guy wrote in to complain that they ran an article on those no-playing long-haired rock 'n' roll punks, and that they should cover nothing but real guitar players like Segovia. The band that the article was written about? The Jefferson Airplane...
I also read Guitarist and Guitar & Bass from the UK--they're a little pricey over here in the US, but they're good reads too.
