I have one of those. I had a HOG and then gave it to Buckweed because I wanted the POG2 due to it's smaller size. In short, it's not as good as the HOG and I only ever used the octave settings on the HOG.
I regret buying the POG2. EHX makes the best octavers for harps in my experience, the POG, POG2 and micro-POG are fine but the HOG is better.
Buddha, I read your comments about HOG and POG in a Gussow & Bailey video and that made me interested. This was the only thing my local store had and when I tried it I felt, wow this is fun. It´s good to know there is a HOG for the future!
