The Boss SD-1 Super OverDrive Pedal is an awesome guitar effect stomp-box pedal by Boss.
At Haworth Guitars we love this Boss SD1 Super OverDrive Pedal's classic smooth Boss overdrive tones, the tone, drive and level controls offering a wide-range of classic overdrive sounds, the 9-volt battery or AC adapter power options, the five-year warranty and it's quality metal construction which can withstand the harshest gigging environments.
Here is what Boss say:
WARM, TUBE DRIVE SOUNDS
The SD-1 Super OverDrive pedal produces the warm, natural distortion of an overdriven tube amplifier while maintaining the subtle nuances of a player's picking technique. This is one of BOSS' more subtle and smooth overdrive pedals, perfect for blues and rock.
Compact overdrive pedal with warm, smooth overdriven sounds
Unique asymmetric overdrive circuitry for a classic, natural tube amp growl
Tone control provides precise adjustment of drive sound
