BOSS SD-1 Super OverDrive Guitar Effects Pedal

With the release of the OD-1 in 1977, BOSS had inadvertently created an entirely new breed of stompbox - offering a natural overdrive in a compact pedal form to guitarists for the first time in history. Oozing with rich even-order harmonics, the unique asymmetrical clipping circuit offered a faithful replication of the gratifying sound and feel of a driven tube amp - but at safe listening levels. Four years later, this iconic design evolved into the more flexible SD-1, which offered an active tone control for fine tuning the treble response, as well as subtle circuit tweaks to deliver more low-end body.

Features

• Genre-defining BOSS overdrive sound
• Unique asymmetrical clipping circuit produces tube-like overdrive characteristics
• Mild-to-moderate drive tones with focused midrange and tight low end
• Ideal for use with clean and slightly driven amps
• Also works great for bringing tightness and definition to high-gain amp tones
• Stacks well with boost, overdrive, and distortion pedals

Overdrive Perfection

From beginners, to seasoned pros - the SD-1 gives you instant access to inspiring sounds thanks to it's natural behaviour and a slight mid push inherent to the circuit design. SD-1 pushes the tone of your guitar in the most important places, so you cut through the mix with unparalleled warmth, clarity, and lush presence. Lower drive settings are perfect for rhythm parts, while pushing the drive up lets you pull off thick, musical lead lines. Highly sensitive to input gain, SD-1 gives you access to a range of different overdrive flavours with a simple tweak of your guitar's volume knob.

The One Pedal Every Player Needs

The SD-1 gives you access to the perfect drive tones for any style of music thanks to it's organic character and responsive drive and tone controls. Push your favourite clean or lightly-driven amp into a mild overdrive that's perfect for classic rock and gritty blues, all the way through pop, country, jazz, and beyond. SD-1 is also perfect for driving high-gain amps and other drive pedals, offering a focused midrange, tight low-end, and a beautifully smooth high-end for heavier tones and solo sections.
