Product Information

Guitar pedals as we know them were invented in the early 1960s. Most pedals you see on the market today (including mine) are clones of circuits that were made 20, 30 years ago. That’s not bad. It’s just the way it is. We already have wah, distortion, reverb, and all these awesome effects. These days, the art of pedal making is more about finding your own unique stamp to put on an existing circuit, effect, or sound. The more experienced among you are probably wondering why I am bothering to post about the Boss SD-1 since it is essentially just a Tube Screamer which is a very well known and researched circuit. Well, I did this because I enjoyed it mainly. Another reason is I've seen a few requests for information about true bypass on boss pedals and this will get you there. Lastly I build on veroboard and existing layouts which specifically cater for the SD-1 are PCB based. Such as the PCB for the tube screamer hosted at tonepad which can also be used to build an SD-1 but which doesn't provide a bill of materials for the SD-1. The SD-1 has been such an important pedal for guitar players that Boss has released a few variations of this timeless classic. The signal comes in and passes through R1 and C1 (input cap) and passes a resistor to 4.5v (R2) which is the bias for the transistor (Q5) being used for an input buffer.

In 1981, the now-venerable Boss SD-1 pedal redefined overdrive tone. Based around the revolutionary asymmetrical clipping circuit from the OD-1(one of the 3original Boss compact stompboxesfrom 1977), the SD-1 wasadored for deliveringrich, organicand highly-musical gainwhilepreserving the core soniccharacteristicsof aplayer's guitar/amp setup — with a subtle mid-boost to add clarity and punch! In this article, I'm going to show you several pedals that are just unashamed clones of other pedals. Let’s be honest. This is more for my own amusement than anything else, but it’s also an interesting peek into the pedal world, where plagiarism is straight up not a thing. You really can (shamelessly or not) completely clone another maker’s pedal, put your name on it, sell it, make some money, and retire like a king in Patagonia, a la the Dread Pirate Robert. That said, there’s a right way and a wrong way to clone another maker’s pedal. It’s the difference between making counterfeit ten dollar bills and writing the musical Hamilton. These pedals I'm about to show you are some of the most shamelessly cloned copies of pedals I've ever seen in my life. Like, amusingly so. You’re gonna enjoy this. The signal goes into the next opamp stage where it meets the tone control which actually boosts the highs as well as rolls off the highs (as mentioned in the last paragraph). R9 here helps to set the gain along with the tone control itself while C6 rolls off even more highs.Country music uses pedals differently than other genres. Explore the style's effects history and learn to use stompboxes to get that twang. Read more… 40 Years of the BOSS SD-1 Super Overdrive Hi, thanks for the great write-up! Concerning the Boutique mod, is the value of .055uf for C2 correct? It seems like and odd (non-existent?) value.

Drive section sounds great especially on a cleaner / at the edge of breakup set amp, but I don?t necessarily use it for this purpose. The SD-1 has been a mainstay in the pedal market for over 40 years, largely down to its simplicity and versatility. As well as using the SD-1 as an Overdrive, its transparent tone perfect translate to use as a Booster. Sometime in the early 1970s, Elk Incorporated made the Super Fuzz Sustainar. Not a Sustainer. A Sustain ar. Yeah, this is a completely different pedal than a sustainer. I mean, it’s spelled differently, so how can you argue with that kind of logic?
