Just a heads up from UltimateGuitar.com
"Today in UG world, we'd like to announce the launch of a new Ultimate Guitar Tabs HD app feature called the Tonebridge."
"Basically, it's an add-on that also works as a standalone app. It allows you to get the exact same guitar tone of 1000+ legendary songs." (from UltimateGuitar.com).
Visit the Ultimate Guitar site for more info.
Download the app from Apple App Store for free. Don't know if there is a version for Android OS.
