The Joyo R-03 is a pure British OD and Distortion (see Friedman BE-OD). Sounds like stacked JCM Marshalls. The great thing is the highly tweakable EQ and tone section with six knobs that makes it an amp in a box. Bass, Mids, Highs, Presence controls to dial that perfect tone on whatever amp you're using. The new R series also has some cool ambient lighting on the bottom and top of the pedal casing that is new to the pedal game and makes it stand out.
