Meris Hedra Pitch-Shifter

I really wanted to work this pedal for me. I love what it does. However, the operation is so frustrating and in addition, not precise, you are more or less guessing what scale and what intervals... it would be perhaps better if the dials were larger and maybe if the knobs clicked into various position... I find it not precise and more of a guesswork. Also the knobs are a bit flimsy and I worry they would not last very long... Other than that, I think it is an awesome pedal. But I will return it and opt for alternative, perhaps for POG or Micropog even though that will only give me octaves and sub octaves and no delay...
