Who wins on what

Ranked by what users actually praise

Overall Impression

Its versatility comes from two parallel circuits blended by the Color knob. Commenters repeatedly describe the OS-2 as a Swiss-army-knife pedal, able to mimic various amps, genres, and even other drive pedals depending on how the Color, Drive, and Tone knobs are set. Multiple users say the Color knob controls a mid scoop/hump and is the real key to unlocking usable tones, with sweet spots often cited around 9-12 o'clock, letting one pedal cover blues, rock, and metal territory.

Many owners kept it for years or even decades as their main drive pedal. Several commenters mention owning the pedal for 10, 15, or even 20 years, calling it their main distortion or an 'under the radar' gem. Others recall it as their first pedal ever, bought as teenagers with limited gear, and credit it with introducing them to overdrive and distortion concepts, with some still gigging with it regularly today.

Detractors say it sounds thin, unfocused, or gets lost in a mix. Some users found it thin and whiny, or that it 'tried to be everything but seemed to do nothing well,' preferring separate SD-1/DS-1 pairings or pedals like the Rat, Keeley BD-2, or Precision Drive instead. Others note low-end roll-off, noise issues, poor dynamic response to pick attack, and inconsistent behavior with solid-state amps as reasons they moved on.
