Tools, Tones and Toys for Guitarists
Original info: Unlike conventional noise gates, the IBANEZ NB 10 Noise Buster is capable of cutting out noise not only while there is no signal flow, but during actual playing as well, thus providing far more effective noise reduction. A FREQUENCY control lets the musician eliminate noise components without impairing the envelope or sustain of … Read more
Originally produced in the early 80s, the SD9 was the distortion brother of the classic TS9 Tube Screamer. It ranges from mild overdrive to fuzz territory without losing articulation. The easiest way to describe the SD9 circuit is to say it’s half of a Tube Screamer, with a Big Muff tone stack. Original units only … Read more
Here’s a rare one from the 70s by Ibanez. It was originally marketed as the OD-850 Overdrive II (not to be confused with the OD-855). But since the nature of this pedal is more distortion/fuzz territory, it wasn’t a great name and it was changed to the Dirt Box. Whatever you want to call it, … Read more
The TS808 layout I post a while back has always bugged me. It’s a real tight squeeze in a 1590B and I wanted a Tube Screamer layout with onboard pots. Well, I finally drew one up and I like this one. It’s laid out for the TS9, but all it takes is 2 resistor swaps … Read more
Been meaning to do this one for a while. One of the most classic effects ever, the Tube Screamer has been used by just about everybody. This layout is for the original TS808 circuit, but you can also build the TS9 on it as well. Just swap the 100Ω resistor coming off the emitter of … Read more
This one was a request. I removed the input/output buffers and the original switching scheme to allow for true-bypass switching. There is one jumper (the original had 6!) and a couple things that bug me, but I’m probably the only one who would care, so I won’t worry about it. Update Feb 25, 2022: Had … Read more
Here we go with one of my personal favourites. To me, the sound is simply amazing. As Dirk’s notes on the schematic suggest, you won’t be saving any money by building this. New ones sell for pretty cheap and one should be able to score a used one for a very decent price. I still … Read more

There are two dual opamps, and one half of the other is completely unused in the original. So i used the remaining half as a buffer for the reference voltage. D1 and D2 are your clipping diodes. Should be easy enough to add a third switch to act as a diode clipping switch.
Request. This layout adds a Timmy type bass control to the TS808 (but with the lugs swapped round so bass increases as you turn clockwise) . I could have just added this to the existing TS808 post but think it’s worth separating them to show two distinct build options. I managed to shift things around … Read more
