pedal input, and connect the pedal's output to the loop RETURN jack. One or more
pedals may be connected in series within a pedal loop. It may be useful in some cases
to combine similar types of pedals into a single loop, where only one of the pedals will
be used at a time. If more than one pedal is used in the loop, then connect the loop
SEND to the input of the first pedal. Connect the output of the last pedal to the loop
RETURN jack. Turn on the pedal(s) to be used so that when the loop is activated, the
pedal effect will be heard.
Pedal Loop 4 as SW3
It is possible to use the 4 th bypass loop as an additional 3 rd function control switch
(SW3). For example, as an additional amp channel control or amp tremolo switch, etc.
th
When doing so, the 4 loop is no longer available to be used as a pedal bypass loop.
The final output from the pedal effect chain is then taken from the jack labeled
OUTPUT (between the PEDAL 3 RETURN and PEDAL 4 SEND jacks). Leave the LOOP 4
rd
SEND and LOOP 4 RETURN jacks empty and use the OUTPUT-N.O. jack for the 3
normally-open switch control function.
Pedal Loop 4 as an A/B switch
Pedal Loop 4 (or Pedal Loop 3 if Pedal Loop4 is used as SW3) can be configured as an
A/B switch by connecting the loop's SEND jack to destination 'A' and connecting the
OUTPUT-N.O (or OUTPUT if using Loop4 as SW3) jack to destination 'B'.
Placement before amp or in amp effects loop.
The Switch Dr. can be placed either before the amp input or in the amp's effect loop.
It is possible to use the Switch Dr. both before the amp input and in the amp's effect
loop, but to do so requires the use of one loop. For example, you could have two pedals
before the amp and one pedal in the amp's effect loop. In order to do that, you would
use Switch Dr. loop3 SEND to the amp input. Then take the amp effect loop send and
go to the Switch Dr. loop3 RETURN jack. Then the Switch Dr. OUTPUT-N.O. would go to
the amp effect loop return. With this method, you will always need to have Switch Dr.
loop3 ON in order to pass through the amplifier's preamp section.
Alternatively, a DB11 Loop Expander can be added to the setup which can provide an
additional 4 loops that can be wired in the amp's effect loop.
