Only ever lived on a pedalboard so in great condition. As is, no original box or instructions but the manual is available online. Any questions please ask.

From the manufacturer:

Increase your sound with a couple of backup singers, an expert engineer and a ton of gear – all with one simple stomp box. Whether you’re electric, electro-acoustic, pro or practicing, Harmony Singer means that your vocal presentation will rock just as hard as your guitar.

You won’t have to brush up on your vocal arranging skills - Harmony Singer does this for you. It instantly analyzes your guitar chords so that when you hit the foot-switch, your harmony backup group is in tune and on time. When it’s this easy, you’ll find yourself using harmony in songs you wouldn’t have otherwise tried.

Our sister company TC ELECTRONIC is renowned in the pro-audio community for the quality of its reverb algorithms and styles. Harmony Singer comes from this lineage, delivering reverb effects in three incarnations: room, club and hall – and you can mix each to the exact feel you want.
