I just got a Jamman and I am having a hard time figuring out the echo function. I am starting to think that the unit may be bad. Basically, I am setting the mode to echo and I do get the default delay. I tap the tempo and get no echo, but it sounds like it is a punch in loop. Is there a special configuration the LEDs have to be in. The manual indicates something about a "P" being in the display. Thanks, Dave PS: any other loopers doing hard disk recording and into bands like My Bloody Valentine, Her Space Holiday, Stereolab, etc...?
