I thought I’d post a separate thread about this with it being a totally new layout to avoid confusion during comments in the thread. A few things about the last layout irked me and so I’ve done a fresh layout which ended up 1 column narrower and so makes it less tight in a 1590B. There are also less links required, includes the reverse polarity protection diode and supply current limiting resistor found in the original but which I omitted from the first layout, and makes better use of the space IMO. Anyway, now you can make whichever layout you prefer.
Information from the builder:
Works very well with other pedals or distorting amp giving this fat and warm overdrive character.
The pedal is also super dynamic, from clean to overdrive just by using different touch of your hand.
Gearmandude’s comparison between the BJFE Honey Bee and the Mad Professor Sweet Honey Overdrive. This could help you decide which one to build using the layouts here:
