I've had this Boss DD-7 Digital Delay pedal for a few months now, and usually when playing with other people I just have it in analog mode with a subtle vintage echo, to get more of a "live" sound (which is funny, since we're playing live). However this pedal has all sorts of other capabilities, including long delays and reverse delays. What are some actual techniques that you guys use to implement delay in with live jamming? Our group is a drummer, myself and a slide blues guitarist, and sometimes we get into jamming trippy stuff, and this thing could step it up to a new level if I knew how to use it correctly. Mostly I'm asking, how do you get use out of long delay effects?
