Intended for guitarists, the BOSS OD-200 is a drive and distortion pedal offering many familiar BOSS tones in a relatively compact footprint. The pedal offers 12 different types of distortion from overdrive to metal tones to contoured drive. You can control these effects with a three-knob tone stack, level, and drive knobs. You'll also note a Parameter knob, whose function changes depending on the effect you select.
In addition to the 12 distortions, there are 15 switchable boost types. You can place the effect in parallel or in series. With series, you can fashion stacked drives, complete with post-gain level controls. In parallel, you can achieve side-by-side blends, which can result in eccentric tones.
The effects provided herein are achieved by means of a 96 kHz, 32-bit signal path to achieve a high-quality sound in every instance. The bypass path is buffered to preserve your tone, even across long cable runs. There are four memory slots provided to save combinations of parameters and recall them when you desire.
A control/expression input allows you to continuously control parameters using a separately available expression pedal. It also works as a control input for external switches. MIDI connectivity is possible via two 3.5mm jacks for the input and output.
The pedal can be powered by three supplied AA batteries. Alternatively, you can purchase a separately available power supply.
