I've had mine for about 2 years.I've gotten some very cool stuff out of it,but it's not very reliable, Turns out 14 seconds is about a sec or 2 less than the lenght I need which is frustrating ,I end up playing a little bit faster than I really want to to get a certain kind of groove feel,that's long enough to build some call and response. I really really like the reverse and half time features,and I use the dynamic,ducked delay alot. It randomly malfunctions,the tone has been getting steadily tinnier for the last 6 months or so. I wish I could have a pedal that I could visually set loop length,change it ,and slice and dice samples,like on a DAW or computer set up. ...Anyhow re:the DL-4 delay modeler, this is among the best gear I've had - and maybe the most versatile. Much better than the Lexicon which, being digital, has less bottom end and depth whereas the Line 6 is...analog bliss baby! It's far more intense than the Alesis Bitrman distortion which many rave about here - and which is totally smoked by the DL-4. Recommended here for any ambient, atmospheric or other far out music sampling because it is so extremely versatile in effects you can mix.I've not seen anything in a moderate price range that has this kind of versatility.
