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)

Amazing for the price, so much overdrive

Nice little taskmaster. Ability to break down the tones is great. Nice little toy

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.

This pedal provides beautiful, crystal clear low to mid gain tones from almost clean with a hint of breakup to light distortion. There are two entirely independent channels which can also be stacked. Each has it’s own pair of hard / soft clipping switches providing 4 clipping modes (overdrive, distortion, both off, both on). Even with both off there is a lovely transparent break up on a higher gain setting. With all of these options the sheer range of tones achievable from this high quality pedal is incredible. Another affordable high quality product from Joyo

Build quality is positive, a really nice metal case and it feels sturdy. The light bar thing is a bit pointless though, I'm not sure what it's for (each side has status lights anyway). Tonally it's generally good sounding. The clipping options are very subtle and only do anything with the gain set high. The taper on the volume controls is a little weird though - both volume and gain need to be well above half to get unity gain. The downside for me was the same I've had with other Joyo R Series pedals - the footswtches aren't mechanical, they're clearly pressing some sort of contact switch insde the pedal but both sides emit a massive pop when engaged. Oddly, I have the "Hot Witch" fuzz which has almost silent switching so it may be a variable. There was also some sort of annoying static noise in the background when either side was engaged which faded after about a second - almost like a noise gate kicked in. Weird. I did ponder tolerating the faults as the unit was decent sounding, but in the end the niggles were too much to take and it was returned.

Very robust, great switches and design. As a new convert to Joyo stuff, I’m happy to report that this King of Kings pedal follows the trend of great value for money gear from this company. Their stuff is usually a clone of other pedals but they do a very good job of it at a very reasonable price. I now own the K of K, Vintage Overdrive (tube screamer clone) and Dyna Compressor (Ross clone). All 3 do a great job. Very happy.

Amazing! Love it

Excellent pedal

Great tones for price point, transparent mid tone heaven.

The Joyo King of Kings (Dual Crunch) is a dual overdrive pedal, meant to give an analog sounding distortion. It can be set for very subtle overdrive (distorts only when playing more aggressively), or full overdrive, where the lead guitar has a very beautiful violin-like tone and sustain. I like all the adjustment options that come with this pedal, so you can customize the tone just to your liking. The construction, and even the packaging, are top-notch. Seems to be low noise also.

Though the foot switches are silent type and they don't make a click sound, they make an audible "pop" sound when engaged. The most noticeable situation is when a reverb effect is engaged. Besides that the tone is good, at least for me, but I couldn't bear the "pop" sound every time I engaged the foot switches. So I returned it.

It’s a soft spying pedal with great drive.

t’s a great pedal for the price, and it really does improve your tone, it adds clarity, presence, and that extra 10% that makes everything feel more alive. But don’t expect a true King of Tone at this price point. One thing worth mentioning is the texture of the sound. When I switch from this pedal to my Tumnus or my OCD, the tone suddenly feels cleaner and more polished, almost like a sound engineer tightened everything up. With the King of Kings, there’s a slight “busy” character in the upper mids, not noise or hiss, but a subtle frequency layer that makes the tone feel a bit more crowded. It still sounds good, but it’s not as dry or refined as higher‑end drives. Overall, it’s a very solid pedal with great tone enhancement, just with a slightly less polished character compared to more expensive overdrives.
