Ease of Use: This is a new Boss harmonizer, after the PS-5, and it's quite similar to it, but there are some things that make the difference. The controls are pretty easier and very intuitive, you can quickly learn how to use the four knobs for all the different functions. You cannot customize most of the effects, but they sound pretty good. // 7
Sound: With this pedal you can have different effects: pitch shifter and harmonizer, detuner, super bend. The pitch shifter works well, it's reliable and easy to use, but it can slightly change the sound of your distortion, if you use a pedal.
The harmonizer is good and accurate, it's a bit better than the PS-5, the only problem is that if you use the distortion of your amp, the two (or three in some ways) notes of the Harmony make a lot of noise, but using a distortion pedal before the Harmonist it sounds perfectly. The selection of the key is easier than before, you can separately choose the key and Major/minor.
The detuner is like a little chorus, it's quite useful for some arpeggios, though for the rest is not so important to improve the sund of a solo or something like that.
The super shifer is simply a Whammy effect, it's a bit uncomfortable to use it because of the "rise time" and "fall time" settings of the knobs, that can take some time, but you can add an expression pedal and with it the super shifter is the perfect alternative of buying a Whammy pedal. // 8
Reliability & Durability: I would not label it as a "must", but it's very helpful to have it, especially if you want to harmonize to make a very melodic solo; you can also exploit the pitch shifter if you don't want to change the tuning of your guitar, like you're in a gig and you don't want to waste time or change the instument so many times. // 7
Overall Impression: This pedal is useful for all the styles and genres; I play Metal and the Harmonist is always on with melodic songs. Between all the harmonizers that have been produced, I think this is the better now, and if someone really needed one, I would recommend this. An only great defect: pay attention to the tuning of your guitar: the Harmonist is very sensible and precise, with the guitar not tuned perfectly it will sound bad. // 8
