Why is my Marshall amp pedal work?

I just bought a Marshall Valvestate combo vs 100 (AMP awsome by the way!) And when I went to try it I plugged the pedal in the amp and nothing happens, no LED light up on the pedal or anything. Please help!

The Marshall uses a FET switch on the pedal. Usually must be connected before the unit is on, so that means the climate is using open, or closed. Make sure to clean the plug and re – try, but make sure PWR Disconnect the power to reset it. Also, make sure both channels are set different, so you see chan 1 (rhythm) and Chan 2 (lead), not so much with the configuration similar or not notice the change. If you do not burn the diode in the pedal, it is easy to replace and Marshall will be set by a price. Try to take the pedal to the guitar shop and have the test than in other Marshall to isolate the problem. Sometimes the FET switch is closed to spring to close, despite the switch works, the connection is marked closed. Good luck … I hope it goes well.
