Nice little toy ## 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.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent clone, recommended *by A***R on 16 July 2026* Amazing for the price, so much overdrive ### ⭐⭐⭐⭐⭐ Nice toy *by T***L on 5 July 2026* Nice little taskmaster. Ability to break down the tones is great. Nice little toy ### ⭐⭐⭐⭐ Good budget pedal *by C***S on 3 January 2024* Has a good range of tones but it's hard to get the sort of slight low gain tweedy grit of the American Sound pedal. I have replaced it with a much more expensive Bogner Blue Ectasy which suits my needs better but that's about peronal requirements: it's not a criticismof the Joyo, which may well be exactly what you need for crunch and solo. ## Frequently Bought Together - JOYO Dual Crunch Pure Analog Circuit Overdrive Effect Pedal with Independent Clipping for Electric Guitar - True Bypass (King of Kings R-20) - JOYO DC 9V Guitar Pedal Power Supply (800mA -1A) AC Wall Charger Adapter with 4 Way Daisy Chain Pedal Cables (8.8 FT), Compatible for Most Effect Pedals (Tip Negative) - SONICAKE Delay Reverb 2 in 1 Guitar Effects Pedal Digital Levitate --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/500241711-joyo-dual-channel-overdrive-guitar-pedal-pure-analog-circuit-independent](https://www.desertcart.us/products/500241711-joyo-dual-channel-overdrive-guitar-pedal-pure-analog-circuit-independent) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-12*
