The Box of Metal is a high-gain distortion pedal with a built-in noise gate, made by ZVex. Premier Guitar groups it with the Distortron and the Box of Rock in the maker's line of dirt boxes1.
"high-gain distortion and gate"
What it does
As a high-gain distortion, the Box of Metal pushes a guitar signal into heavy, saturated clipping, the territory of hard rock and metal rhythm tones rather than the lighter breakup of an overdrive or the wooly collapse of a fuzz. The built-in gate is the feature that sets it apart from most distortion pedals: it cuts the signal when you stop playing, silencing the hiss and hum that high-gain circuits otherwise amplify along with the guitar1.
For a player comparing ZVex dirt boxes, the Box of Metal sits at the aggressive end of the range1:
- Box of Metal: high-gain distortion with a noise gate, the most aggressive of the three1
- Box of Rock: leans toward amp-like overdrive1
- Distortron: a punchier, mid-focused grind1
