Not for the Meek or the Lazy
I'm a pretty traditional player, blues and classic rock/metal. I find it really hard to beat a Gibson straight into a Marshall. That's all I need. If I use pedals at all, it's usually a pretty standard chorus or delay, at least until now. This is really an amazing pedal! Sure, it's easy to get completely useless sounds out of it, but with some work, there are tons of incredible tones in this box.
It's a mistake to think of this thing as just a harmony generator. It's more like a delay with control of the pitch (and modulation, and envelope, and number) of the repeats (even if the delay is set to zero). The quality is good enough to use on any source, not just guitar or bass. That makes it a useful studio tool, another reason I added this to my collection.
I gave this a 4 because it's not a plug in and play pedal, not that I expected it to be. Honestly, I don't think the presets do it justice, either (they aren't bad, but...). It takes some work to get it to sound good. Once you do, though, there are a seemingly endless variety of things it can do. Sure, it's not as powerful as a full-fledge harmonizer, but it's a fraction of the price, too. If I was a full-time producer or recording engineer, I'd get one of Eventide's uber-super-mega-boxes. But, I'm not; I'm a guitarist first and this pedal gives me everything I need.
The bottom line is that this is an incredible, creative tool, always ready to reward a little work with new and inspiring tones.
