Well, gave it trial run this morning. More extreme settings were fun, but a little bit overkill for the setting. More experimentation to be had, but I found quite a good subtle setting with low Octave settings and a slight boost to the two eq knobs. This gave a subtle boost to the sound without being overly effected.
It may sound like too much, but this actually sounded good used in conjunction with my OC-2, using the Meatbox more as an eq pedal to emphasise the octave effect.
