Small Sound / Big Sound makes so awesome, gritty pedals and I love his designs. I never got a chance to play any of his pedals but always lusted over the demo videos. The Mini was posted on FSB and Brian (Owner of SS/BS) added some advice on the schematic to say the least. My buddy David over at Effectslayouts made the etchable layout I used in this build.
SS/BS describes the mini as a fuzzy JFET overdrive and I think that’s a very accurate description of this pedal. It can go from sounds of a nice tube like OD to a failing tube OD to straight up fuzz. The Bias knob can help get it to tight sounding to a velcro/spuddering sound.
I did a reverse etch and made it look a bit “dirty” to match its sound. I am not 100% sold on these knobs and might swap them out.
I used the Grind Customs FX optical bypass Lumen
