No distortion, just very strong bass and great depth of sound. I only went away from doubling up when I got an Arrow 3G which with its two stage bass switch really doesn't need the ZO.
For me a two-stage bass boost isn't a replacement for 32-level. I'm way more picky than that, the ideal bass level isn't matter of 5dB differences, I tweak my sound on 0.5dB basis! Guess I'm just too much of a perfectionist.
