This project is based on the schematic posted by David Barber at www.diystompboxes.com for the Barber Tone Pump. The only change from that posted schematic is to tie pin 2 to pin 3 of the Tone pot. All other values are the same. The layout artwork is based on the layout for the Madbeanpedals Silverfox, v3 for the Barber LTD Silver, original schematic also posted at www.diystompboxes.com. Due to the similarities in the projects, the part numbering was kept consistent between the two to aid in discussions if needed. R8 and R9 are not found in the Tone Pump and are marked none in the parts table to avoid confusion.
