TC Electronic's Quintessence Harmony pedal breathes new life into solos, offering a range of modal presets and intervals for rich harmonized sound. The innovative MASH technology stands out, transforming it into an expressive tool akin to an expression pedal. While its application may seem niche, especially if harmonized solos aren't your style, its versatility shines in studio settings. Perfect for musicians tired of mundane melodies, it delivers vibrant chromatic possibilities beyond typical octave shifters. A clever, creative addition to any pedalboard.

A great harmonizer that works great with guitar or bass.

Before I got this pedal, I used to have a Boss PS-6. While I liked certain things about it and I did like it for guitar, I found that it didn't work that well for bass for me as the tracking was a bit glitchy with it (mostly with bass solos). With the Quintessence, the tracking is way smoother, it sounds way better on bass and the pedal is even more customizable than the PS-6. The mash footswitch is great too as you can bend intervals in certain chords as well, which is a handy thing.

TC always pisses me off

If you want to have nice Thin Lizzy/Judas Priest/Iron Maiden etc. harmonies, you have to run it either after dirt/distortion pedal or in FX loop. The manufacturer has not stated it in the manual. In fact, no manual in the box, it can be found only online. So, few days after I sold my MXR Super Badass, I had to buy it again, cause I could not use it with a distorted amp;( What is more, TC is usually misleading about their stuff. In the Flashback 2 manual they used to claim that it has audio tapping function, while it doesn't. Funny thing is that the first video demo for Quintessence had a guy wo ran the quintessence before distorted amp. This is crazy! Last but not least it requires intermediate to advanced harmony/scale knowledge - so definitely not for all.

This is such a Uniquely Powerful little Pedal. The Amazing features that it's able to handle in such a small footprint is incredible and certainly has become my favourite Harmonizer Pedal. I'm so glad that TC Electronic has brought this little Magical Pedal back!

Best harmonizer pedal ever

TC Electronic gear is all-pro quality. This pedal has nearly zero latency and does all of the harmonies you want. And its polyphonic - sounds great with chords. A must have if you need a real working pro harmonizer on a pedalboard.
