The Joyo R20 King of Kings is a classic, vintage-style overdrive pedal. Part of Joyo's Revolution series, the vintage circuitry adopts a 1+1 dual-channel design. This allows the two channels to be used independently, or in series. When used in series, you'll be able to get fierce crunchy overdrive and vintage distortion tones.
Each channel features an independent diode clipping circuit and feedback switch. This will allow you to get subtle nuances to your tone. Each channel offers adjustable volume, gain and tone control, allowing you to really dial in the precise tone you're looking for.
