I found a schematic,a layout (that has a glaring error) and a couple of reviews on this pedal but little else. i am working on building it (i screwed up my grounds so i am bypassing the trannies for now but will fix that when i get home from a day of teaching physics to freshmen) and i was wondering if anyone knew anything about this pedal, or any tips to modify it such as adding a tone pot or tonestack to it, changing the input cap etc. any help would be greatly appreciated and when i am done i will post some sounds. if anyone likes i can up the schematic and layout i am using. thanks and have a good one!

Hi,

Hey if your teaching this to freshmen tell also about how the loadingpoint affects preformance.
If you make an experimentboard mount potentimoeters for the Rc's and make your freshmen listen and decide what sounds good.

Have fun

Hola! Yo arme este, y no me convenció. Es un circuito de Ff tradicional con los valores alterados. Creo que seria buena idea agregar un par de trimmers para polarizar los transistores (yo use 3904). Tambien serviría agregar el tone stack de big muff pi. Tambien habia agregado un pot 100k justo antes de la salida, a modo de volumen. No se cual es el error que mencionas mas arriba... saludos!
