Radial Voco-Loco Mic Effects Loop & Switcher

Mic Preamp and Effect Loop

The Voco-Loco is a foot-controlled microphone preamp and effects loop switcher that enables a vocalist or acoustic instrumentalist to incorporate guitar effects pedals into their signal path.

Connect any mic to your guitar pedals
The Voco-Loco combines a microphone preamp with a guitar pedal effects loop, allowing a lead vocalist, sax or trumpet player to add guitar pedals to their audio signal path just like an electric guitarist adds effects for soloing. Simply plug your mic into the Voco-Loco via the XLR input, connect your effects pedals using standard ¼" guitar cables, and then send the output from the Voco-Loco to the input on your mixer. Now with the touch of a footswitch you can add your favorite delay, reverb, distortion or wah-wah to any mic'd up instrument or vocal - the options are only limited by your imagination.

Voco-Loco Applications
