TC-Helicon’s Harmony Singer is a multi-effects unit that helps guitarists create guitar-controlled vocal harmony with adjustable Tone and Reverb. It can generate one or two harmony voices and uses the company’s Adaptive Tone, which combines EQ, Compression, De-essing, and Gating that adapts to the user’s voice and vocal range. The Tone button can be toggled on or off, and when on ensures smooth dynamics and clear presence. It also has three Reverb types – Room, Club and Hall – with adjustable level control.
