The JF-35 sounds like a Randall on 'roids. The gain is incredible, as you'll see in the YouTube videos of the pedal being demo. If you want incredible gain at an affordable price, look no further. The hardest part may just be deciding between this pedal and the other stomp boxes in the same arena. Joyo has rock, metal, blues and every other tone nailed. 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 (other than the signal that is supposed to be distorted). That's thanks to the quality components, such as the quarter inch input and output jacks, a clean DC power circuit (9V 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!
