The Sidewinder is a very unique and versatile effect unlike any other pedal on the market today. It is a stereo switching effect that can be used in many different ways, with 2 inputs and 2 outputs that can be used in different configurations. One way to use this effect is to have 1 input and 2 outputs going to 2 amps. When the effect is engaged your input will alternate between the 2 different outputs, kind of like a stereo tremolo or panning effect. This is a great way to use 2 amps for a very psychedelic stereo effect! When the effect is bypassed you can choose to either have your signal go to both amps, or just one.
