As well as having the Forums where you can discuss all things guitar, the forum also provides the following boards, and loads more.  Please check them out.  That said, you don't need to be in a band, or even play an instrument to enjoy the forums.  Just jump in and post anything music related. You'd be crazy not to give it a go.

Company shout outs board. A place for Guitar and accessory manufacturers,  to shout about the products, and promote any of your gear.  Just start a new topic in this board, and remember to add links.

Promote your band. So bands / solo artists can promote themselves or their music, or gigs. Start a new topic in this board, and add links back to your sites, your music etc.

Teaching Services.  If you teach people to play the guitar, then advertise your services in the appropriate board, again just start a new topic here in this board. Don't forget to leave a link.

Gear Reviews. Here you'll find a selection of user gear reviews. If you have a piece of kit, and would like to tell us what you think of it, go ahead.
