R-21 TORNADO - JOSé DE CASTRO SIGNATURE DUAL-CHANNEL OVERDRIVE

R-21 TORNADO Dual Channel OVERDRIVE is a signature pedal for JOYO's artist: the Grammy Awards Winner, and professional Spanish guitarist: Jos de Castro. JOYO has been discussing, and revising it over and over again with him and has finally been recognized by him. In BOOST Channel, the overtone is quite spacious, beautifying the treble and bass nicely. While in DRIVE Channel, he loves the unique tone, it's clean, smooth and rich, covering wide frequency bands.
