David, try tapping in shorter echo times for practice, and do this BEFORE you play any audio into the jamman. as soon as you hit the 'tap', the green led should light, and it will turn off when you tap the second time. sometimes, when doing multiple taps to get the general tempo of a song, you can mistakenly leave the 'tap' ON, so to speak... just make sure your last tap turns the green led OFF. then you will see the green led pulsing with the tempo. that's the way you want it... and the P means that the echo mode is in bypass. hit the bypass switch and you should see a number on the screen, 1-16. 1 is the lowest feedback, essentially one repeat. 16 is 100% feedback. all the numbers inbetween are various levels of feedback. you can adjust that by the pot on the front panel (i've forgotten what it's labelled as) hope this helps... rich ps. i'm doing hard disc recording, and my influences of droney, spacey guitar laden bands are similar to your references. shoegazers unite! >I just got a Jamman and I am having a hard time figuring out the echo >function.
