TC Helicon was founded in 2000 to make audio tools specifically for singers. Its early VoicePrism rack processor provided harmonies and vocal effects; VoiceLive floor units and the later VoiceTone pedals brought those tools to live performance. JustPedals listings include VoiceTone processors for pitch correction, doubling, harmony, reverb and vocal dynamics, including the T1, C1, D1, R1 and H1. These are microphone-facing processors rather than guitar effects, and the right model depends on the vocal function needed. Music Tribe acquired TC Group, including TC Helicon, in 2015.

Specialist effects alter the signal in ways that do not sit cleanly inside one established family. They may use granular processing, frequency shifting, resonators, freeze or sustain, bit reduction, ring modulation, feedback networks or combinations of several techniques. The relevant distinction is the underlying process, its tracking or latency, and how completely the dry signal can be blended or replaced.
