Rowin Shaper

The Rowin Shaper is a distortion pedal made by Rowin. What sets it apart from most distortion boxes is that it is built around wave shaping: instead of only clipping the signal the way an overdrive or fuzz circuit does, a wave shaper redraws the shape of the waveform itself, and the new shape is what generates the distortion and its harmonic content.

What it does

A wave shaper works by remapping the waveform. Every point of the incoming sine-like guitar wave is pushed through a shaping function, so the output wave comes out with a different contour, and that contour is what creates the harmonics a player hears as grind, edge or color. The maker's description of the wave-shaping approach puts it this way:

Because the harmonics come from the reshaped wave rather than from simple clipping, a wave shaper can produce distortion textures that sit outside the familiar overdrive, distortion and fuzz categories, which is the main reason a player would reach for one over a standard overdrive or fuzz pedal.
