Distortion pedals in general can be divided into three basic approaches and distortion families: specific distortion pedals, overdrive pedals and fuzz pedals.

Distortion pedals are the most modern approach to simulate or replace a tube distortion by the means of transistors or diodes. Some of them are on par with tube preamps.
Overdrive pedals are special because they have the clean guitar signal mixed to the distorted sound, resulting in a mild but harmonically rich sound. The preferred application is to push a downstream tube amp into its own distortion and tightening the sound at the same time.
Fuzz pedals feature the most ancient circuit architecture. Their exclusive properties are that they do not attenuate the bass frequencies, but the high frequencies instead, resulting in a “fuzzy” (not “creamy”) sound.

We have faithfully modeled the most prominent vintage distortion pedals. In addition, we have created a number of novel booster and tone-shaping effects that could not be realized in the analog domain.
