So I have a Digitech Drop, which is cool for simulating detuned tunings. It's also got an octave down function, which is cool. Lately though, I've started thinking about getting a more encompassing pitch shifter to swap out with my Drop, so I can do more cool wacky pitchy stuff when I feel like it.

At this point, I think I've narrowed my choices down to the Boss Pitch Shifters and the Pitch Fork. Now I'm trying to figure out what would be best for me between the PS-2, PS-3, PS-5, PS-6, and Pitch Fork. I don't really know exactly what I want, other than octave(s) up, octave(s) down, and harmonized intervals in between. Not really sure if I want perfect tracking or not so perfect tracking. Controlling pitches with an expression pedal might be cool if/when I ever get an expression pedal, so maybe I could rule out the PS-2. I was researching the Boss pedals earlier today, taking notes and trying to learn the features of each and what exactly sets them apart, and after a while my head started to hurt.

The PS-2 or PS-3 might be cool for the 2 in one pitch shifting/delay combo, especially since I don't own a delay pedal. But I tend to shy away from pedals that have like 5 million different, knobs, sounds and functions. Not that these pedals have a lot of knobs, but it's clear you can coax quite a lot of sounds out of them, before even getting into the delay settings. I'm the kind of guy who gets overwhelmed with possibilities and can't get anything done. So the PS-2 and PS-3 might keep me a little too busy.
Anyway, I figured it was time to open up the floor to you guys with your thoughts and suggestions. Pitch Fork vs. the PS family? Other suggestions? I've ruled out a bunch of other pedals like Wizard Of Pitch and Pitch Bay. It would be particularly helpful if anyone could chime in with their personal experiences, and the benefits and features of each pedal from the Boss PS line.
