BJF/MP/Bearfoot
Mad Professor Ruby Red Booster
For now, only the booster/overdrive section, might add a separate board for the switchcable bypass buffer later on… 2N5952s is getting really scarce but 2N5457s or 2N5458s is usually a good sub. Just mind the orientation! Schematic is avaiable HERE.
Mad Professor Blueberry Bass Overdrive
This is basically a higher gain version of BJFE Blueberry Bass OD since it has an added pre amp stage (Q1). Note that originals had the now obsolete BF244A transistors with DGS pinouts. I changed the pinouts for more accesible transistors. 2N5457s should bias up fine and sound good.
