uhmmm. my friend has that green line 6 delay pedal. i don't know if that was the one you were referring to, but it's pretty cool. it does a ton of stuff.
i have that ibanez analog delay....i can't think of the model number right now and i'm not sure if it's here or not. it sounds super cool.
There's tons of delay pedals out there. How are you going to use it? Through your amp's effects loop? As an outboard effects processor for your mixer/computer? What type of music do you play? etc....
