Matt Rasmussen, founding member and guitarist of the band Rose of Jericho (8 songs so far in RBN), posted an excellent video review of the Squier 5 months ago (Part 1, Part 2 and Part 3). An admitted tech geek and avid player of RB, Matt really liked pro guitar, and since that review has posted several clips of himself playing pro charts with the Squier (with an inset of the rolling chart) on the band's YouTube channel.
Of particular interest is something that I just saw on that channel yesterday (looking for links to his review to post in a reply here): this clip of Matt playing a pro guitar chart for "Buried Cold", one of Rose of Jericho's RBN songs. Tools for authoring pro guitar charts aren't supposed to be available to RBN authors, but apparently there are some . Cool to see a guy playing his own music in the game . (It's notable that he breaks streak several times--what's up that??? If you can't FC your own composition ...).
Dare we hope that we'll see pro g/b charts in RBN tracks in the near future? (And legacy upgrades, too--I've already double dipped for "Buried Cold", buying the original in May last year and a recently released RB3 version in April).
