Compare, contrast, tell me stuff... I have no idea what I'm getting into with delay pedals...different kinds, analog vs. digital, etc etc. But, I am pretty sure that I want one after seeing a band this weekend do some pretty cool **** with one. I like the idea of the Line6 DM4, especially because you can attach an expression pedal to it to vary the delay time...but I've heard that digital delay sounds crappy in certain situations. When...I have no idea... Teach.
