Boss SD-1 Super Overdrive Pedal

Get all the distortion of an overdriven tube amp with the Boss SD-1 pedal. Tweak the tone control knob to dial in some grit, or go for a smooth, round tone.

The SD1 produces the warm, smooth distortion of an overdriven tube amplifier while maintaining the subtle nuances of your picking technique. Boss's unique asymmetric overdrive circuitry delivers a genuine overdrive effect for a classic guitar sound. A tone control is also provided for precise tonal adjustment.

Smooth, round, fat distortion--the sound of tubes being pushed past their limits. The overdriven sound that the electric blues and rock were built on. That's the sound you'll get with the Boss SD1 Super Overdrive Pedal. Its unique asymmetric overdrive circuitry delivers a genuine overdrive effect for a classic guitar sound that still maintains the subtle nuances of your picking technique. And so you can get your tone just right, there's a Tone control knob between the Level and Drive knobs. No, there's nothing complicated about this pedal--just some great engineering and a sound that stands the test of time. A lot of digital distortions out there could take a lesson from the SD1.

About Boss Pedals
The history of Boss reads like the history of guitar effects. From their legendary CE-1 chorus pedal (the big gray box that started it all) to the world's favorite line of compact pedals, they've been responsible for more guitar innovations than just about anyone else.

Boss's compact pedal line-up began in 1977 with the classic OD-1 Overdrive. Its warm, smooth overdrive sounds and breakthrough Boss pedal features (heavy-duty construction, rubber pads on top and bottom, recessed read more control knobs, silent switching, a built-in LED and easy battery replacement) immediately set it apa

all guitarists need an od at some point. So its nothing special, and these types of pedals arent supposed to be. Its job is usually done well no matter how much you spend.
I equate overdrives like wasabi or cayenne pepper...its got no real flavor of its own until added on top of something. Although, id say the sd 1 adds a nice high mid to your tone. Lots of extra grit on tap sure out there would be curious to know that. Just remember..its overdrive, not distotion. Overdrives are transparent and sit on top of a sound, thus if you play clean channels with an od on, youll still hear the clean signal clucking under it. a distortion is for masking or creating a channel. If you play a clean channel then kick on a distortion, you basically just created a dirty channel.
Just perfect actually
Ease of Use
a caveman can do it
Its a boss...their stuff has always seen the worst and managed to keep working.
Considering how many idiots will spend 200 and up for something as simple and plain as an od, this is an absolute steal. It does exactly what an overdrive is meant to do. Od pedals have no business in the boutique world.its like people trying to make a gourmet french fry and charging a premium for it. at the end of the day, its still a classless french fry. An od is still an od.

Never needed it
The Wow Factor
Lets say this again...its just an overdrive. It has no character on its own. Its sole purpose is simply pushing an amp
