USING THE ON-BOARD EFFECTS LOOP
Start by connecting the SEND jack to the input of your effect pedal and 
the output from your pedal to the RECV (receive) jack using standard ¼” 
coaxial guitar cables. In order to familiarize yourself with the setup, start 
with one pedal. This will make trouble shooting much easier. 
Depress the LOOP footswitch to turn the function on, the LED indicator 
will illuminate. Note: If there are no pedals connected to the SEND and 
RECV jacks the LOOP footswitch will have no effect on the sound. 
You cannot accidentally mute your sound because there are no pedals 
connected.
Start with the 3-position LOOP switch on the top 
panel set to BOTH. This way the effects will be heard 
on both channels. You can use this switch to assign 
the effects to one channel exclusively. 
The LOOP WET/DRY control lets you dial-in as 
much of the effects as you like and helps preserve 
the original bass tone. Set the WET/DRY control 
to the 12 o’clock position and adjust to either 
increase or decrease the amount of effect you hear 
in comparison to your original bass tone. In some 
instances, you will want a lot of effect, in others only 
a little bit. Have fun and experiment.
