The Boss OD-3 is a pedal designed to provide an elegant tube overdrive sound. Featured is a dual-stage overdrive circuit and three simple knobs: tone, volume, and gain. Designed to be used as either a normal overdrive (50 volume / 50 drive), a boaster overdrive (100 volume / 0 drive), or a dist-pedal (30 volume / 90 drive), the OD-3 is rated as elegant and focused on the clean channel, while it’s over-the-top and loud with the gain channel.
