Donny and I are adjusting to our "retirement rigs" ... although I will still have to work another 10 years or so before I can actually retire. My plan is to use the SD60 and my guitar rig for all live shows, and keep my studio running as is - Korg SV1, PA4x, Yamaha SX900, Digital and acoustic drums, electric, acoustic and bass amps .... all the software goodies, and great mics from Neumann, Warm audio, EV, Shure, Sennheiser and others. Once I get the SD60 (I know I've said this many times) I'm set. I will put all my energies into learning, and perfecting the best way to make these tools SERVICE ME.
For you guitar guys ... heres' the rig that I use with guitar/drums/looping and tracks. The mixer has aux/mute outs that allow me to run the iPads into 2 channels (to feed the harmonizer) then BACK into the main mix through the main out of the Voice Live 3. It essentially operates as 2 independent mixers. This model also supports 2 wireless mics that plug in with a single USB dongle to channels 1 & 2 - sweet.
