Based on the classic LPB-1, with the option of building the screaming bird variant too - with the added "Plus" that allows you to use a 6mm trimmer instead of the external pot, if you want to to set the volume and forget!

This board is great on it's own and has a super small footprint (only just bigger than a 16mm pot!) but also works fantastic with other pedals - combine it with another board into one mega box - go nut!
