## Description

desertcart.com: JOYO Dual-Channel Overdrive Guitar Pedal, Pure Analog Circuit with Independent Clipping (Hard/Soft) per Channel, Stackable A to B, True Bypass (King of Kings R-20) : Everything Else

## Features

- DUAL-CHANNEL OVERDRIVE — 2 INDEPENDENT CHANNELS, STACKABLE A→B: The King of Kings delivers two completely independent overdrive channels in one pedal—each with its own Volume, Gain, and Tone controls. Use Channel A for a warm, low-gain rhythm tone and Channel B as a clean boost for solos, or stack them in series (A→B) for cascading, singing lead saturation. Players describe it as delivering beautiful, crystal clear low to mid gain tones suitable for everything from blues to classic rock.
- INDEPENDENT CLIPPING PER CHANNEL — 4 DISTINCT VOICINGS: Each channel features its own pair of clipping diode switches—giving you four distinct voicing combinations per channel. Hard Clip delivers tight, modern crunch with percussive attack. Soft Clip provides smooth, compressed overdrive with tube-like warmth. Both switches off yields a transparent, open-sounding clean boost ideal for pushing your amp's front end. Both switches on combines both clipping styles for maximum saturation. Pro tip: the clipping effect is most noticeable at higher Gain settings; at lower gain, the differences become more subtle.
- PURE ANALOG CIRCUIT — 3-KNOB CONTROL PER CHANNEL: The all-analog signal path delivers organic, touch-sensitive response that reacts naturally to your picking dynamics and guitar volume knob adjustments. Each channel features dedicated Volume, Gain, and Tone controls—simple, intuitive, and instantly familiar. Dial in everything from edge-of-breakup warmth to rich, harmonically saturated crunch without digital artifacts or menu diving.
- TRUE BYPASS & ROAD-READY R SERIES DESIGN: True bypass switching preserves your guitar's natural tone when the pedal is disengaged. Encased in a rugged aluminum alloy, the King of Kings features the iconic R Series ambient LED lighting with 3 modes (Sync, Always On, or Off) via a recessed switch on the underside. The sturdy metal footswitches and smooth, responsive knobs are built to withstand heavy stomping night after night.
- JOYO QUALITY & AFTER-SALES CONFIDENCE: Backed by JOYO's decade-plus reputation for crafting innovative, budget-friendly gear. Important: Powered by 9V DC adapter only (center negative, not included). Rated current: 20mA. No battery compartment. For the cleanest sound and to minimize any audible switch pop, use a regulated, isolated 9V power supply and ensure your amp's input level is set appropriately.

## Questions & Answers

**Q: How does the R-20 King of Kings dual channel overdrive pedal work?**
A: 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

**Q: Can the R-20 be used with two channels in series?**
A: 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.

**Q: Can I emulate classic rock and metal tones?**
A: 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.

**Q: What if it makes noise when I use it?**
A: 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: Q: Why does the pedal make a popping sound when I engage the footswitch?**
A: 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.
