TC HeliconTC Helicon VOICETONE C1 Simple 1-Button Stompbox for Flexible Pitch Correction, Compatible with PC and Mac

looks good, works good

I needed a simple way of adding harmonies to my songs. This is simple to use and works well. Simply play your guitar through and it adjusts to the key or use the dial. I like it. I warn you that if you sing out of tune it will split that into harmonies too! Great box and great value

For the love of all that is holy, don't buy this as a distortion pedal for an instrument! This is a VOCAL effect unit, and this is what it's been designed for.The unit itself is decent, but I don't like having another power supply to plug in.Some advice for musicians who were thinking of getting this as a guitar or bass pedal:Bassists, look at a Boss ODB-3 (distortion), or Big Muff Pi (fuzz)Guitarists, literally most Boss pedals, Big Muff Pi, Fuzz Face

Ease of use.

Ordered a new unit, received a second hand one with no power supply and obviously used. Returned for refund.

This product is simply amazing

Doesn’t work for minor harmonies, for major keys sounds great.

I bought this item as a gift for my son who is a professional singer songwriter. He is very pleased with it.
