Winter NAMM 2013 - Radial
The Radial Voco-Loco is an interesting mic preamp that lets you add guitar effects pedals to a live vocal. There's a low noise Mic pre with high and low EQ. You can supply 48V phantom from the unit.
Additionally, there's send & receive loop so you can patch in stomp boxes or other FX, with a footswitch to actiave and a dry/wet mix level.
