This is a board for a dual-effect 125B pedal: OCD v2 and EP Booster.
This probably won't be an ongoing product. These are just leftovers from a one-off project.
This is an advanced build, with extremely tight soldering conditions, requires a bit of forethought and planning, and has very little documentation.
