I had never heard of this pedal, but had heard people saying that an Eventide Harmonizer was key to getting the later Van Halen sound. Then I saw the You Tube videos of Kent Carlevi and he mentions that he uses one of these.

I'm just using the pedal for a simple and slight detune and adjust the delay to taste.

This sounds like a chorus pedal, but no sweep, and by changing the delay you get a reverb-like depth (if you want it).

This setting is great for a lot of '90s and later slick rock guitar music and I won't be without one from now on :-)

Just got this thing along with an expression pedal and I cant' say enough about it. Even with the limited knowledge I have of the limits of this product, I'm so happy with what it's doing for me now. This thing is great for harmonizing leads! You you have to know your keys. You'll find it frustrating trying to harmonize without a grasp of your key signatures. I run mine through the loop and it doesn't sound thin or plastic. It seems to be a very sturdy box-like all Boss boxes.

If you know your keys, want to expand your sound and just plain want to have a great time with a great pedal, I recommend you get this thing.

And it does this function well. I read some reviews before and was hesitant to purchase but I took a gamble and am glad I did. The intelligent harmonizer works fine - it tracks well and is clean IF you follow the directions: Make sure your guitar is tuned (A=440 Hz) and overdrive/distortion is plugged into the input side, not the output. This seems counter-intuitive but it really does clean up the sound. I have a Radial Tonebone Classic and Radial Hot British pedals on my pedalboard before this and even with that much gain at hand, the harmonized sound is nice and crisp. I tried this plugged into my practice amp - a Vox AVT30 set on overdrive with less than stellar results. I suppose if your amp has an effects loop, that would clean up the tone. I originally bought this just for the harmonized leads in "Hotel California" and it works great for that: I set the key on F#m with the pitch a 3rd above. I use this in our worship sets in church as well. I tried using the detune but it's very digital-sounding: the chorus setting on my Boss ME-30 is much nicer. And I don't have much use for the other features for now. So there you go - for me, an expensive one-trick pony but it does its job well.

I got this to emulate an 8 string sound. Like the John Paul Jones/Diamanda Galas stuff that came out a while back. It does do stuff besides harmony! It can be set for a straight pitch shift down or up! (I dont know why so many pitch pedals only do sub octaves! Some of us want to go up!) The harmony settings are okay, but are in pretty standard (boring ) keys. Almost everything I do is minor 7th minor 3rd-ish so it isnt really my cup of tea. Though I suppose I could transpose and find the right key if I did the math. It bugs me that the whammy mode requires you to stand on the pedal while it is engaged. This is hard to do when you have an expression pedal to work with the other foot!

This is by far the Best pedal i have ever bought. Ive made my share of Mistakes when buying pedals. Normally your either disappointed with a pedals performance, or it just matches your expectations. Though i can tell you this one, shatters expectations.

Most of You are probably looking to Create harmonies with this pedal. Word of advice: PUT THIS PEDAL EITHER IN YOUR EFFECTS LOOP, OR BEHIND YOUR DISTORTION PETAL! That is if your interested harmonizing distorted leads. If you dont, when you switch to distortion with the Harmonies on, it will overload the sound of your amp, making it sound Fuzzy. Tho if arranged properly you should be able to get Crystal Clear Spectacular harmonies .

This pedal is not for beginners. You NEED to know your key signatures, and know which notes lie with in them to fully take advantage of the brilliance of this pedal.
