Maybe we should have just one thread for this (maybe there is one and I didn't see it)
I searched (google+talbass) but found nothing.
Do you know what kind of effect is Philippe Bussonnet using in this video?. You can get the idea watching just the first 1-2 minutes. The audio is out of sync but you get the idea... http://www.youtube.com/watch?v=8oGJYLv9DFY
It's like a very bassy fuzz sound. Very well controlled and thick but you can identify even the lowest notes
