From what I've heard he didn't like being mic'ed because I don't think he got the dynamic range he wanted. He used 70s-80s era piezo pickups that IMHO sounded rubbery. If I'm not mistaken in the Reckoning stuff the ran the piezo to the monitors and FOH and the mic was for recording. I remember Grisman busting his chops a bit for his acoustic set up, contending that it wasn't acoustic unless the sound moved through the air first.
Technology for acoustic guitar has really come a long way since 1995. I'm sure he would've moved on from those Takamine/Alvarez piezo systems. as better stuff came along. Not that I thought his tone was bad, it was about the best that was out there to get what he wanted across. There's just a lot more options now.
