I really didn't want to blow that kind of cash right now (I was shopping lower priced Env Filters like the DOD and Digitech), but after reading all of the reviews, they really didn't seem worth it. So after all of the reviews, etc, it believe this is the right one for me. It's seems plug and play and has the tone I'm looking for (I hope). They advertise that it has some more bottom than the DOD 440 (which is what is was modeled after). Comments, etc? Looking forward to getting it!
