How does the R-20 King of Kings dual channel overdrive pedal work?

The R-20 features two independent overdrive channels with Volume, Gain, and Tone knobs that allow you to set different tone and gain levels for each channel. You can use one channel alone or both in series to create a wide variety of tonal variations

Can the R-20 be used with two channels in series?

Yes, you can connect two channels in series and use the first channel as a base tone and the second channel with more gain for heavier distortion. If you test Channels A and B individually, the tone exhibits low gain rather than very high.

Can I emulate classic rock and metal tones?

Yes, the R-20 can emulate a wide range of classic rock and metal distortion tones, which is especially suitable for players who are looking for vintage tones and hard rock distortion.

What if it makes noise when I use it?

The probability that the noise of the effects is caused by the use of incorrect power supply, it is recommended to use with a 9V DC power supply (center negative, not included) to ensure the cleanest sound and minimize unwanted noise

Q: Why does the pedal make a popping sound when I engage the footswitch?

Some users may experience a subtle pop when engaging or disengaging the footswitch—this is a known characteristic of soft-touch true bypass switching circuits and does not indicate a defect.
