Vocal effects have exploded in popularity over the last few years, as the prices have come down and the technology has become more portable and powerful than ever. Now these effects units and pedals are capable of producing realistic, real-time effects, pitch correction, doubling, de-essing, pitch-shifting, and even multi-part vocal harmonies. Some of our favorites vocal effects pedals are the TC-Helicon VoiceLive 2, electro-harmonix Voice Box, Boss VE-20, and the DigiTech Vocalist Live 2. We also are fond of the TC-Helicon VoiceTone series. So we hope you will check out the reviews on these popular models and find the vocal effects that you enjoy most.
