Rivera amps showcases it's Sedona Amp at Summer NAMM 2007. Doyle Dykes helped design the Sedona, the world's first electronic/acoustic all-tube amp. The amp contains two independent and different pre-amp channels. The first is meant to the deliver the cleanest possible electric sound. The second is meant more for an acoustic input, and works with the tweeter to accurately reproduce the live harmonics of an acoustic guitar.

Ani DiFranco, Staind, Sugar Ray and 311 currently use the Sedonas in their live shows to deliver the clarity they need. Rivera seems to have tapped into a very specific market with the Sedona. See for yourself in this video from Summer NAMM 2007.
