I recently bought this unit, based on recommendations of a friend and the myriad positive reviews. I am finding the use of the Harmonizer function difficult to dial in what I want. Which algorithm do I need to purchase in order to be able to really control the harmony effect? Other pedals I've used allow you to select the key, and the 3rd, 5th or whatever. Since the name of this unit is the Harmonizer, I sure do hope this feature exists.
As a side note: I'm a guitarist and I find 90% of the presets built into the pedal aren't very practical. Why are the presets so "out there"?
