BOSS SD-1W SUPER OverDrive | Premium Waza Craft Guitar Effect Pedal with Analog Circuitry | True Reproduction of the Legendary BOSS SD-1 SUPER Overdrive | Standard & Custom Playing Modes

The Boss SD-1 is a true classic — and after finally adding it to my board, I totally get the hype. It delivers a crunchy, saturated tone that’s perfect for everything from classic rock riffs to smooth blues leads. Tone & Character: The SD-1 has a very distinct voice — bright and mid-forward, with that signature Boss bite. • With gain up: You get a tight, crunchy drive that’s great for ‘70s/‘80s rock rhythm tones and even some lead work. • With gain down: It cleans up well and gives you a snappy, bluesy edge — great for pushing a tube amp into natural breakup. • Saturation: There’s a nice compression to the drive that gives it sustain and smoothness without losing clarity. Versatility: Works great as a standalone overdrive or as a boost in front of another pedal or amp. It cuts through the mix thanks to its EQ profile and pairs well with both single-coils and humbuckers. Build Quality: Like all Boss pedals, it’s built like a tank. Reliable, sturdy, and ready for stage or studio use. Final Thoughts: The SD-1 is a no-frills workhorse — bright, crunchy, and saturated in all the right ways. If you’re chasing classic rock grit or bluesy bite, this pedal still holds up as one of the best in the game.

This pedal is great. I use it at low gain & level at 100%. It takes the flub out of your bottom end. Tightens everything up & increases your gain. It's been heard on countless recordings. It's easy to use. Remember to unplug input jack if a battery is connected. ( I use a power block) it's one of the cheapest high quality gain pedals out there. If you're on the fence just buy it. You can't go wrong with ANY BOSS pedals

Fantastic! I do own a Mxr Zakk Wylde Od, but I generally keep it elsewhere with an old Marshall valvestate amp. This pedal is fantastic, takes your gain from 4 to 8 no issue! I run it into a Prs MT 15 and dont have to crank the volume to get the saturated gain I want and sustain for days! It can push more noise out, but I tame that with a cheap noise gate coupled with it. Overall this pedal for the price is great, plug up change settings to taste, and go.

Good sound and great for a first pedal

This is it. Here you are looking at an SD1. I can honestly say that through total hours used this particular yellow boss stomper is probably the pedal I have accumulated the most out of any in my board. Does it sound perfect? Not so much on its own. The tone can sound sort of thin at times and the tone knob is deceptive at first and like any pedal needs to be learned and sweetly nuanced. Where this little yellow titan shines and is truly ascendant to the upper echelon of significant pedals is when applied to a chain or used with a high gain setup on an amp. Personally I usually run my SD-1 into a big muff pi and the way that they add to eachother is truly impressive. Simmilar to the ibanez tube screamer this pedal "plays nice with others" and can elevate distortion effects and even modulation effects up into something new. Want your synth 9 to get dirtier and heavy? SD-1. Playing through a gain setup on a Marshall and your solo is coming up? Stomp that SD1. Octave pedal isn't enough of a giant "sound wall" for you? How about that SD1. One of the peices on my board that doesn't get swapped and is always early in the chain. Highly recomend purchasing (unless you have no other effects or distortion options, consider and Ibanez tube screamer in that case)

I don't know how I've made it through life this long without getting an SD-1. Along with the Ibanez TS-9, this is one of the most omnipresent overdrive pedals in history. I recently got a Marshall Origin 20H amp, which is meant to sound like an old Plexi and thus has a low level of gain out of the box. I got this to overdrive the amp a bit at low volumes. And wow does it sound good! It got me that classic 70s AC/DC, Led Zeppelin, Aerosmith, etc. sound just by turning it up. I've always wanted a Tube Screamer, but the SD-1 is just so much cheaper. And it's built to last like every other Boss pedal. If you want to give your tube amp a little boost, look no further than the Super Overdrive.

The boss SD-1 is an awesome pedal. My humbucker pickups break up nicely with just this pedal plugged into my amp. I would describe it as a "tight crunch" tone, or a light distorted sound. And when I put the SD-1 before my distortion pedal-goodnight! It pushes my distorted gain to a whole new level! I'm very happy with this purchase. Most guitar players are going to like this pedal.

Great !!! I love it !!
