sound mangling devices?

["nick@12testing.net" <nick@12testing.net>]

Hi - I've got my looping side sorted out with a jamman and a zoom g2, 
but I'm looking for sugegstions as to what units will give the 
maximum amount of sound mangling power at a reasonable price? 

It's important that there should be plenty of knobs for live 
performance. I've got an airFX and that's great, but would like a bit 
more control so I can repeat effects with some confidence!




All the best,
