The Quintessence Harmonizer from TC Electronic is a powerful, feature-rich harmonizing pedal offering eight default harmonies and three TonePrint harmonies, with seven diatonic scales and a custom scale setting. In addition to TonePrint, the Quintessence is also equipped with TC's MASH technology, which serves to bend your harmonized note up to the next interval within the scale for an expressive control without having to add another pedal to your board.
