I'm looking for a good delay pedal that will allow me to save at least 2 different sounds and access them with a footswitch. Basically a short (almost reverb) delay and a long delay. I just want a solid, quiet, reliable unit -- don't need a ton of other features and settings. I was thinking about the Line6 DL4 unit, but the reviews are generally not good with regard to reliability. What do you recommend?
