TC Helicon's Harmony Singer is a vocal effects pedal designed to provide guitarists with high-quality vocal harmonies, reverb, and tone control. Here are the key features of the Harmony Singer:

1. Guitar-Controlled Harmony:

   • Up to Two Harmony Voices: The Harmony Singer can generate up to two harmony voices that are controlled by the guitar input.

   • Harmony Types: Choose from various harmony types, including thirds, fifths, and octaves, which are automatically generated based on the guitar's chords.

   • Three Studio-Quality Reverb Types: The pedal offers three different reverb settings: Room, Club, and Hall, allowing you to create the perfect acoustic environment for your vocals.

3. Tone Control:

   • Tone Button: Adjust the overall tone of your vocals with a simple tone button, which can help you cut through the mix or smooth out your sound.

4. User-Friendly Controls:

   • Rotary Controls: Easy-to-use rotary controls for adjusting harmony type, wetness (mix of dry and wet signal), and reverb.

   • Master Switch: A master switch to turn the harmony and effects on and off.

5. Mic Control:

   • Remote Harmony On/Off: The Mic Control function allows you to remotely turn the harmony on and off using the switch on compatible microphones like the Sennheiser e 835 fx or TC-Helicon MP-75.

6. Compact and Durable:

   • All-Metal Construction: The pedal is built with a rugged all-metal construction, making it durable for live performances and studio use.

   • Compact Size: The compact size makes it easy to fit into any pedalboard setup.

7. Power Supply:
