I'm real fussy about stuff I endorse, I will NEVER ever say to y'all that I play something if I'm not using it and honestly dig it. I do not get paid to use anything, but I do get discounted or free stuff sometimes. I don't have any exclusive deals and often use things not listed below, I'm a bit of gear slut and not particularly faithful ;) Check them out, all seriously great tools for making happy sounds in your ears!
Surprisingly, for a free site, Justin Guitar offers a few free tools and apps to help guitarists with their lessons. The most interesting of these are the series of apps available for download on the iTunes store (so they will only work with iOS). These include a Time Trainer Metronome, a Guitar Note Trainer, and a Blues Lick app – which brings together Justin’s weekly Blues Lick series.
