Harley Benton Custom Line Dual Loop Switch

What this pedal does do

The input lead plugs in on the right side.
The output lead plugs in on the left side.
Channel A send and return sockets are on the back side (the side facing the audience) in line with footswitch A. Channel B send and return sockets are on the back side in line with footswitch B.

I used an external 9V power supply for the leds.

With the toggle switch on:-
Pressing footswitch A will bring channel A in. Pressing footswitch A again will switch channel A out.
Pressing footswitch B will bring channel B in. Pressing footswitch A again will switch channel A out.

With the toggle switch off:-
Pressing footswitch A will bring both channel A and channel B in. Pressing footswitch A again will switch both channel A and B off.
Pressing footswitch B does nothing.

What this pedal doesn't do

I was hoping this pedal would switch between channel A and channel B and vice versa by repeatedly pressing footswitch A when the toggle was off, but it doesn't, so I returned it.

I didn't experiment long enough to tell whether the channels are in series or parallel when they are both switched in.

I think Thomann should maybe revise the product description to make the available functions clearer.

It works fine if the actual functions are what you are looking for and you are careful with your feet! The toggle switch should definitely have been sited farther away from the footswitches.
