Less than a week ago, i bought a new Marshall Echohead (delay pedal). Today, it's completely screwed. I did not drop it or anything. When it's on, there's the red light, but sometimes there's no delay. And then sometimes there is delay, but all 6 modes sound like the multi tap delay. And when it actually works, there is only one repeated note on the reverse delay. (the pedal itself has 6 delay modes). Oh and sometimes there's this horrible noise coming out of it. Conclusion: my pedal is fu**ed and I don't know why.
try checking the power supply or replacing the batteries
