I already have one dual loop switcher which is excellent, but doesn't have LED's. That didn't seem important when I got it, but it really is good to have an unmistakable indication of what is switched in and out. The instruction sheet mentions the on/off toggle switch, but it really fails to explain clearly what this does. I still haven't quite worked this out. In one position the LED's never go completely off, just bright to very dim. I don't know what is going on there? The overall finish and style are excellent. The LED's show when each section is on or off and this switcher is only about half the cost of my other unit. There is no ground lift capability, but I did a direct swap comparison with the other unit and in my setup there is no performance difference between ground connected or lifted. This is with a fully isolated power supply, so loops through power leads don't occur. Update 27-02-16: I have now cleaned the toggle switch with 3 drops of methylated spirit dropped down the lever, flicked up and down 10 to 20 times, shaken out and the whole unit left touching a hot pipe overnight. Result = everything now works perfectly and the LED's go completely on and off as they should. So now the rubber feet have been removed and replaced with Velcro strips and the box is securely fitted to my pedal board. Complete success! The other reviewer accurately describes the way this unit switches. (Better than the instruction sheet).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 LED's. 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 B again will switch channel B 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.
