From the post
After John K got better results putting a buffer before the circuit I thought it would be a useful to do a second layout incorporating a blend pot. This almost certainly will make the effect more useful with bass, and if you want the effect 100% you can simply leave the blend pot in the extreme counter clockwise position.
For info about the effect see the original Funk Machine V2 post.
Schematic
This is a board layout, a drawing of where each part goes, and the post may link the schematic it was drawn from. Open the layout at Tagboard Effects. No KiCad fragment has been drawn for this circuit yet.
