This is the only effects device I ever used-

2 channel delay that can run the delay at the same time as either the flanger or chorus.
4 button foot pedal that required a stereo 1/4" cable.
It freaked out about 10 years ago and I never found anyone to repair it.
Found an earlier version on ebay but the sound is not as good and kind of "leaks" between the channels.
Ooops- scratch that, I also have both analog and digital wah pedals.
