super luper by a guy called tarekith you can download from his website

http://tarekith.com/misc.html - down the bottom download ableton dj effects v5

theres some other alright stuff on there too but the looper is bad-boy , its a rack made up of beat repeat, eq8 and a filter - you can get some really good loops and doubling going on.

I also use fuzzplus (free on the audio damage website) and frohmage (free on ohmforce site) for a bit of dirt when needed

theres a good thread on aldj about effects
