Guitar players rejoice! The closing of the Online Guitar Archive, which shut down about a year ago along with other popular destinations for guitar tabs, hung guitar players out to dry as far as quality tablature went. Music publishers such as the National Music Publishers Association flexed their muscle and silenced guitar strings everywhere.
Musicnotes is currently negotiating a return of one site, MXTabs.net, with major publishers. The negotiations focus on the splitting of advertising revenues. Once launched, the site will limit itself to tabs approved by publishers.
However, as we've seen with sites like SpiralFrog, reaching agreements with quality publishers can be quite difficult, and failed negotiations can sink the sites into the depths of irrelevancy.
