Of course, it is an overdrive pedal! A special little wonder that provides clarity and transparency, not usually associated with TS-based pedals. There are no mid-range dents, no bass loss, no audible compression, and a compelling sound, thanks to the body control, a dual gang stereo pot that helps you dial the perfect tone.
Holy Moly! I had a blast with this one!
As you can imagine, when making these PCBs available for you, we have to build plenty of Tube Screamer ™ based circuits to allow you to build the best sounding devices out there, and here comes what you already could read in the first line.
This one is outstanding good and dethroned my long-time loved custom build TS I did just for myself. Let me say this clear, sound-wise it does one thing major different from the million other versions of its kind. But first, does it still sound like you expect it? Yes, but it has that little extra no matter what way you turn the pots, and it’s super hard to describe. You got to hear it and even better compare it to your favorite Screamer; you will be surprised. Now back to that one difference I mentioned before. The Body control instead of the normal Tone Knob. A dual taper Potentiometer that sits with one part in front of the first opamp stage and with the second part behind is insanely effective and gives you a bass loaded tone, the classic sound or a really mid pushed Flavor metal guitarists use to tickle their amps even harder without getting lost in the mix.
Rumors say some guys built this with two individual Pots instead of the dual Taper and liked it. Personally, I did not try this yet.
The Building Doc applies to both the 1v0 and 1v1 versions of the PCB. The only distinction between the two models lies in the arrangement of the controls, so please use the drilling template that corresponds to your version.
