I originally got this pedal to free up the Micropitch setting on my H9, as the H9 cannot use two presets at the same time. I'm so glad I got this pedal - of course you can get Van Halen 1984 tones through the Hagar era, but there's so much more on offer. It's a very useful delay and chorus as well. In fact the best way to think about this pedal is Pitch + Delay + Modulation (Chorus). You can use all three together, or only 1 or two, your choice. The 5 presets make it great for easy access to the most used presets.
Like all Eventide gear - reading though and understanding the functions is key, though, to be fair, this pedal has been thoughtfully designed for simplicity - this is a pedal to dial in with your ears, with knobs rather than via milliseconds or cents with digital readouts - if you enjoy turning knobs and work through the 'dual' knob functions, you'll really enjoy this.
Even used with clean tones this pedal is winner - get some very slick LA Studio clean tones. And using this pedal lower in the mix just adds some great dimension - it's like a secret sauce for tone hounds.
10 - 15 years ago, the cost of achieving the tone was in the multiple thousands (you would need an Eventide H3000 or maybe two 910/949) - now this pedal brings those sounds to mere mortals so we can enjoy the the tones of the gods and rock hard high on the top of Dream Mountain.
