I got a beautiful Brooklyn Burst G2420 for Christmas and I'm absolutely loving it. I stayed away from the T version with the licensed B60 Bigsby because of the 'numerous enough' comments about tuning issues. But now I'm rethinking and wondering how much of a task it is to retrofit the B60 on to the guitar. Does it require drilling? It looks like the bottom screw hole of the existing bridge might be exposed because the hinge piece that screws into the side of the guitar is longer that the B60. Thoughts?
