With 11 modes and up to 2 seconds of delay, you'd be hard pressed to find a better bang for your buck outside of a dedicated rackmount. This is best for either the experienced experimental musician or the solo guitarist who wants some backup. Digital delay pedals record the input from the guitar, and after a short interval, play it through the amp. Along with various time modes, the DD-6 adds a cool tap-tempo feature, a mysterious reverse simulation, and a hold feature. The Tap Mode makes this the ultimate live pedal as delay times can be tapped in on the fly via the Boss FS-5U footswitch. The Reverse Mode gives you a kooky mixture of the original sound mixed with the reverse. The hold feature is great for atmospherics or droney passages. The coolest thing about the DD-6 is that the decay trails off even after you've disengaged the pedal.
