Thanks cdog. the loop is in the circuit somewhere, I can't remember where exactly, from memory there are three places you can splice it in, pre, repeats, or post repeats, or somewhere else, It was a big headache, but did work, i think i had to add a buffer and boost also, the inside got a bit cramped, as I refuse to use pcbs mounted pots, preferring my own layout of knobs etc. echobase is is a fun build, but never again with the loop.
EDIT: turns out there is a thread here on how someone else did it, looks pretty similar from memory. http://www.madbeanpedals.com/forum/index.php?topic=19063.0
