The Fangs Metal Distortion pedal delivers intense, brutal high-gain distortion. From ultra-tight thrash tones to thick, wall-of-sounding doom metal distortion, it delivers devastating distortion sounds. ---------- GAIN Adjusts the amount of drive, from smooth and silky distortion to wicked metal distortion. VOLUME Distorting the sound compresses the signal, reducing the output level. You can adjust the output level with this knob, but be careful not to turn it up too much and disturb your neighbors. Mid-range characteristic selector switch: You can switch between three types of mid-range characteristics, which are the deciding factor in distortion tone. BASS Adjusts the boost/cut of the low range. If you mainly play single notes, a higher setting will produce a smoother, more body-like tone. TREBLE Adjusts the high frequency boost/cut. Thru-bypass specification Fangs Metal Distortion is a true bypass pedal, so when it's turned off it doesn't interfere with the tone at all, preserving the original tone of the instrument.
