I Hear a Weird Noise, What Can I Do?
Most often, noise issues are related to the power supply feeding the New Revelation. The first thing to check, does the power supply meet the requirements to power the pedal (9V DC 300mA). Supplying voltage above 9 volts can damage the pedal and supplying 9V with not enough current capacity (300mA) will cause unpredictable behavior and noise issues.
Is the pedal being supplied with its own isolated power port (no daisy chaining). Daisy chaining power from pedal to pedal can introduce unwanted noise.
