The Boss OS-2 is a low-end to mid-range compact overdrive/distortion capable of mixing the distortion and overdrive effects to many different degrees. It features a color control knob that allows users to adjust the balance of overdrive and distortion as well as drive and tone knobs for further tonal control. Additionally, the OS-2 sports a tough, compact design.

The OS-2's color knob allows users to adjust from maximum overdrive to maximum distortion with a great number of variations in between, offering a high degree of customization. Furthermore, its drive and tone knobs provide control over the OS-2's 'heaviness' and tone, respectively; this allows the OS-2 to produce both heavily distorted sound and a more subtle distortion/overdrive. Meanwhile, the OS-2's durable build and compact size makes it highly portable.
