Yes. The pedal features dedicated Link In and Link Out jacks, which allow you to connect two Decimator II units together. This configuration enables synchronized stereo noise reduction, ensuring both channels react identically to your signal.
The Decimator II is designed to be highly transparent. With a dynamic range of over 100dB and low harmonic distortion, it focuses on removing unwanted hiss and hum while maintaining the integrity and character of your original signal.
The pedal operates on a standard 9VDC power supply and has a low power consumption of 35mA. It is compatible with most common pedalboard power bricks.
Absolutely. It is widely considered an industry standard for high-gain setups because it effectively silences the heavy background hiss generated by high-gain amplifiers without sacrificing the clarity of your palm-muted riffs or sustained leads.
