i don't own one, but i ALMOST got one a few months back....
supposedly you can dump the delay stuff you do into a jamman sampler (i think)
i'd check out youtube vids to see if it's something you'd like.
when i was going to get it, there was one on ebay for around $200....
i think i decided against it b/c the delay is just like the DL8 delay...so no varispeed options...
i had a boss rc20 yrs ago....to me the jammans seemed similar in operation...more memory of course, can save more loops (99 vs the rc's did like 11 or something)
