Into The Unknown Bill Of Materials (BOM)

This PCB is designed for two board mounted LED's, one for 
bypass indication and one LFO rate indicator.

* These are current limiting resistors for the LED's. Use the 
appropriate value for your LED type.

The ”LED” hole (next to the output connection hole) should be 
connected to the ground for LED bypass on your stompswitch.

Other things not included in the BOM but good to have: 
enclosure, input and output jacks, DC jack, led bezels, 3PDT 
switch and knobs.
