JOYO JF-315 Metal Head Distortion Mini Guitar effect pedal is taken from the 3rd generation of JOYO pedals, the Ironman range. A great guitar Metal rock sound is hard to achieve from a guitar pedal, but the JOYO Ironman mini pedal pulls this effect off perfectly, it is perfect for the Metal Head within you. From jaw dropping hard fat chunks to a screaming high gain, the gain is picked just right. The added EQ section with Mid and High controls, give you lots of control and you won't need the LOW.
