i tested the Agro again in bandcontext yesterday and paid special attention towards low end loss. At first, there is a feel that some lows get cut, but i blame that on the boosted mids. When you set the level by ear and have a little contour dialed in, the mids make the whole thing sound louder and thus, you're likely to choose a lower setting to achieve unity, resulting in a little less bass in the signal. I tried with other settings and could not detect any loss of lowend.
Inspired by the Broken Dick Peanut Gallery soundsample i took my other OD and set it to low Gain and boomy sound to feed the agro. The result was kind of brutal but totally worth to keep in mind for further experimenting.
