Interesting DIY i found that i made lastnite:
http://www.instructables.com/id/Looper/
except i modified it by wiring in a volume pot to the output since the signal is extra strong and wired it so i can get a dry signal while the loop is engaged, otherwise the way it is outlined only the loop is heard. nice lo-fi cheapo budget version of the boss loopstation but much more limiting, though thsi thing could be great for those into noise.
