OVERVIEW
The Voco-Loco is a mic-to-effects interface that enables the vocalist, sax,
trumpet or harmonica player to use pedals just like an electric guitarist.
In other words, you connect your microphone to the Voco-Loco and it
converts the signal so that it may be used with guitar pedals. The signal
is then sent to the PA system where it is processed as usual.

CHORUS DELAY
You simply prepare the effects in advance by turning on an echo and a
chorus pedal and when ready, engage the pedal chain by depressing
the effects loop footswitch. When the song is over, you stomp on the
footswitch again to turn off the effects. In between songs you set up the
next effect with your pedals on standby, ready to be engaged as needed.
The cool thing about using the Voco-Loco with a variety of pedals is
you can decide which effects you want to use for a given solo without
having to necessarily follow a given path. This fl exibility opens the door to
unique and creative effects which can enthrall an audience during a live
performance or spur on creativity when you are jamming.
Understanding the signal fl ow
Following the block diagram below, the microphone feeds a studio quality
mic preamp which then feeds a 2-band EQ. This is used for tone shaping
the dry mic signal. The balanced signal is then converted to a ¼” hi-z
output that is suitable for guitar effect pedals. Separate send & receive
controls let you optimize the signal-to-noise and eliminate distortion. The
output of the effect pedals is then brought back into the Voco-Loco where
you adjust the tone and blend the original dry signal with the effects for
the ideal mix. The fi nal mix is then sent to the PA system via the balanced
XLR output.
