JOYO JF-35 sounds like a Randall on roids. The pocket metal, of course, is suited for metal and does fine in a hard rock setting as well. One really great feature is the pedal isn't noisy at volume. That's thanks to the quality components, such as the quarter inch input and output jacks, a clean DC power circuit 9 volt DC battery included and other parts of quality including the capacitors, resistors and of course, smooth pots volume and tone knobs. Speaking of which, the JF-35 has a unique mid-range control adjustment, as this frequency range is of more concern in heavy metal than the highs are. Scoop or add grit, just by making a quick adjustment on the huge bright white knob. All told the JF-35 from JOYO audio gets the job done and leaves you with spending cash to invest in strings, cables and all the other essential gear that it takes to make great music. The pocket metal distortion pedal will inspire you and afford you with that modern metal crunch.
