Special Features: Independent Diode Clipping (CLIP) and Feedback Switch. Target Users: Electric guitarists who favor vintage overdrive, classic Crunch, and distortion styles. Covers "moderate Crunch" to "vintage distortion"; intensity can be flexibly adjusted via the GAIN knob. If there is high-frequency noise, it is mostly due to insufficient power supply filtering or excessive gain. It is recommended to replace with a low-noise power supply or appropriately lower the GAIN, and patiently find suitable settings. If the electric guitar pickups have built-in gain, it is necessary to reduce the pedal's gain or turn off the pickups. 1.Within the range from "clean boost" to "mild overdrive". 2.Set low gain as a boost and preserve guitar's tonal characteristics (such as the brightness of single-coil pickups). It is often used to "push Channel A or the amp preamp," and the stacked tone maintains dynamics. 1.Adjust from low to high gain knob to find optimal tone rather than blindly pursuing the maximum. It may easily lead to background noise. This is not a problem with pedal, but a common knowledge related to background noise. Solutions: Reduce guitar's own gain (pickups) or directly turn down Gain knob 2.If guitarists prefer gain stacked, it is suggested to use independent, well-shielded power supply and cables; Also set Channel B to low gain as a boost or add a noise gate 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.
