Haze. It has enough distortion to completely compress your sound to 0 dynamics and make your guitar squeal uncontrollably at any real volume, how much more do you need? The effects card with memory by channel makes it a whole lot more versatile than the DSL.
I've tried both...the 40C is able to get more into cutting 800 territory, the Haze was voiced darker, thicker.
I preferred the 40C...with the EQ you can get it dark and thick as well if needed, it just cut better with a band....records well to.
