Now you are probably very familiar with with the Boss line of digital DD lines. I must say, their latest incarnation of this pedal may very well be the best I've seen. Boss has been able to improve upon an almost perfect pedal and add some amazing new features. Again, retailing for around $150, the pedal is certainly not cheap and is meant for the serious musician.
The most important improvement is the 6+ seconds of digital delay time that you get with the DD-7. The hold feature allows for over 40 seconds of recording. This is pretty amazing for a stomp box.
