From the vendor
Bjorn Juhl's low-gain overdrive inspired by an old Supro amp, reverse engineered on freestompboxes. A CA3130 op-amp gain stage with green LED clipping in its feedback, feedback loops that shape the high end, a filter at the end of the circuit and a 2N5457 JFET output stage. The post found it a great slightly-dirtier-than-a-booster pedal into a tube amp on the edge of breakup, very dynamic.
Bearfoot Honeybee variant: C5 on the madbean schematic is 220n and is in series with a 4.7K resistor.
