Overdrive Defining Clipping Circuit

Natural & Inspiring ToneIn 1977, BOSS created a completely new style of stompbox with the OD-1, offering guitarists natural overdrive in pedal format for the first time ever. Producing a harmonically rich signal with a unique asymmetric clipping circuit, to give you the satisfying sound and feel of a driven tube amp, but at controllable volume levels.
Four years later, this legendary design developed into the more versatile SD-1, this came with the addition of an active tone control for shaping the treble response and subtle enhancements for more low-end depth.
Warmth & ClarityThe SD-1 gives players of any level to get inspiring sounds instantly, provided by its natural response and the subtle mid boost that's part of its design. It pushes your tone where it needs it, so your guitar always sits perfectly in the mix with warmth, clarity, and rich presence.
Lower drive settings are great for rhythm sections, whilst higher settings are ideal for huge, singing leads. The SD-1 is also very sensitive to input gain, letting you dial in different levels of overdrive just by adjusting the volume control on your guitar.
A Must-Have Overdrive

Perfect For All StylesWith natural characteristics and responsive drive and tone controls, the SD-1 offers the right sound for just about any style of music. Engage the pedal with your favourite clean or slightly driven amp for mild-to-moderate overdrive, perfect for everything from classic rock and gritty blues to pop, country, jazz, and more.
The SD-1 also works great a booster for high-gain amps and other drive pedals, with more mid focus, tight bass, and smooth top end that suits heavier tones and solo playing perfectly.
