Today I decided that I wanted a new overdrive pedal, something that I couldnt readily buy. A new sound. After digging around a bit and looking at the jabillion (yep jabillion) tube screamer clones out there, I came across this little circuit at http://www.runoffgroove.com/ubescreamer.html The “UBE SCREAMER”.
Unlike other overdrive pedals, this one is based on a logic IC instead of your standard opamp.
Someone was kind enough to post their results of this build on youtube If you are interested in taking a peak on what this little circuit can do..
I am going to be implementing a Volume, Gain, Tone, and Variac pots (see circuit) , as well as a 3 way rotary switch to allow for different types of guitar pups and sounds. Another addition is a true bypass switch and the ability to power it off a 9 volt battery or power supply, for this I am implementing a DPDT switch. I had all the parts for the main board in my junk box, so this is a total win 🙂
Now just to find a nice enclosure for it.
