DIRECTIONS
To set up the Uni-Vibe® UV-1 Stomp Box, rst be sure it is connected to the Dunlop ECB04
18 volt AC Adapter and that the adapter is plugged into the wall. (The Uni-Vibe does NOT
operate with battery power.) Plug your instrument into the INPUT jack on the front of the unit,
and your amplier into the AMPLIFIER jack.
Set the three knobs at the top (Speed, Volume and Intensity) to their straight up, or 12 o’clock
positions. Then nd the Effect/Bypass switch, at the lower right. Switch the effect on, making
sure the red LED near the switch lights up. At this point, the effect’s volume will likely be
set too low.
Next, check the Chorus/Vibrato switch at the lower left, along with the LED just above it.
When Chorus is selected, the LED glows green. When Vibrato is selected, the LED glows red.
Choose the mode you wish to use.
Once your Chorus or Vibrato mode is set, adjust the Volume knob for the desired output
volume. Toggle the Effect/Bypass switch on and off, and compare the volume with and
without the effect. For many playing situations, matching the two volume levels is desirable,
especially if you’ll be switching the effects in and out while playing. However, you can also
use the Volume knob to BOOST the overall volume up to 120% (+3dB), by adjusting it so that
the effect’s volume is louder than the clean signal.
Finally, adjust the Speed and Intensity knobs to shape the character of the effect you want.
Adjust the Intensity knob rst. In Chorus mode, it will change the depth of the sweeping
effect. In Vibrato mode, it will change the degree of pitch modulation. Adjust the Speed knob
last. At lower settings (counterclockwise), it will produce slow, sweeping effects. At higher
settings (clockwise), it will produce rapid, shimmery pulsing.
You can also control the Uni-Vibe’s speed with the optional UV-1FC Foot Control Pedal (see
description, next page). When the UV-1FC is plugged into the Pedal jack at the front of the
Uni-Vibe, it takes over the function of the Speed knob, giving you greater real-time control.
It also allows you to easily put the Uni-Vibe in Bypass (no effect) mode by rocking the pedal
all the way back (heel down position).
