« i love it »

So far, there have been no compatibility issues.  I use a Macbook (2.2ghz, 4gb Ram, 320gb HD) with Logic Pro 8 and a Presonus firepod.  Everytime I load it up it works great.
Is the general configuration/setup simple?
There are a few different dials on the face, but after playing around with each one, I was able to get a good grasp of what they do.  I usually just start off with a preset (there are quite a few) and go from there.  


SUITABILITY/PERFORMANCE

So far, no need for a manual.  If you are familiar with audio equipment and you have decent ears, you will get the gist of this unit.  
Are the typical functions easily accessible? 
All the dials are right on the face so I would consider them easily accessible.  

OVERALL OPINION

Yes, it works great, I have one complaint about it but I will address that below.  Overall it seems to process the signal very well and I have yet to notice any latency issues.
What performance are you getting? (if quantifiable)
If I had to quantify it, I would give it a 10 out of 10.  In a nutshell, it is a very powerful distortion unit.  Like I stated earlier, I use Logic 8 which has a bunch of built in processors which includes a few distortion units.  I really enjoy them but the devastator blows them out of the water.  Its gritty, strong (weak if you want it to be) and down right evil sounding.  I really enjoy it and use it much more often than the Logic units
