The Joyo JF-315 Metalhead is the latest in Joyo's newest additions to their pedal lineup. The Metalhead was designed for the discerning distortion fan. Darker and tighter it excels at, of course, Heavy Metal and Nu Metal type sounds. It's deep and chunky, especially good for rhythm riffs and cascading gain stages gives you more sustain than is probably necessary. Yet it is remarkably quiet. It even works well with Shoegaze and alternative tones, the distortion is musical and textured. One special feature of the Ironman series is the cover that flips over the controls to protect your carefully dialed in settings from getting changed accidentally. Set it and forget it! A nice little bonus is the LED light glows through the cover when engaged for a cool visual effect. Features: Flippable cover design to protect your settings. True Bypass. Volume, Gain, High and Low EQ Tone Controls. Sturdy and solid. These were made to last. Uses a standard Boss style 9V AC Adapter. Includes velcro to attach to your pedalboard!
