Bold style: A compact square icon for a distortion effect pedal. Central emblem features a jagged waveform slicing through a shield-like form, conveying grit and impact. Bold, high-contrast silhouette with clean vector lines. Colors: obsidian black base with crimson red and electric cyan accents for edges and waveform highlights. Flat color blocks with minimal shading to ensure readability at small sizes. Subtle bevel on the outer edge to mimic a hardware faceplate, no text. The composition emphasizes a strong diagonal energy, drawing the eye to the waveform crest. Suitable for a pedal faceplate, scalable to icon size, crisp at 1:1 aspect ratio.
