I have 2 of the Xvivve U3s for mics, and a pair of U2s for guitar, as well as a set of Roland WL-20L - use them all the time, but I like having the charging station right in this rig. It's always ready to go when I power up the rack.
Dave, that looks like an amazing guitar rig. Could explain the equipment and how you use it to play guitar, sing, harmonize, play backing tracks, usage of beat buddy.
Thanks,
Mitch
