Specialists in vocal effects processors, TC Helicon have been crafting great-sounding and affordable stage effects for some time now. Their latest compact processor is the TC Helicon Harmony-G XT, a vocal harmonizer that analyzed your incoming guitar signal to generate intelligent real-time harmonies.

The TC Helicon Harmony-G XT also features some useful vocal sweetening effects like reverb, EQ, and compression, and also sports a handy guitar tuner. TC rep Laura Clapp walks us through the Harmony-G XT's functional highlights, and treats us to one of the sweetest vocal performances the Gearwire studio's ever seen (J.-Irving Giles' rendition of Fastball's Out Of My Head notwithstanding).
