I wish there would be an option for pink PCBs
In general but especially for this one
Sad life
Now to this thing
Again we have a fantastic design by Anders of Dirtboxlayouts
And again I will just copy/paste his description of the thing since he is way more capable of writing and stuff:
My take on Roland AF-100 Bee Baa. Ditched the boost switch and one of the tone settings but added two new ones. "Highs" switch toggles between stock (middle position) and two settings that cut some highs:-). The other switch named "Notch" toggles between three settings in the twin notch circuit. Middle position has 10nF to ground which gives a full sounds with lower mids. The two other settings is closer to stock Bee Baa tone with varying degree of scooped mids. Combining those switches quite ba broad variety of tones; harsh and thin to wooly and bassy.
