Just got one of these, the new silver version, and bummer, it has an artifact on the initial note that makes it unusable. Obviously, a manufacturing defect. I checked my bass (tried a few), the cable, and made sure all the levels were right (not overloading the input) and there is a very obvious glitch, like a click every time a pluck a note. And I got this because my EBS compressor is coming apart: the active/passive switch broke and know I have to dissemble the darn thing to switch modes. Shame on you, manufacturers, for making crappy products! So, if you are getting a new BBE Opti, make sure you have a warranty and return policy in place.
