Make this project even better. Don't be shy to be manipulated. Detail level is used. In loop position, loop\nis connected to trigger, gate jack is normalized\nto +12 V, 10 mA -12 V ## Photos ### Photos ## Documentation: * [Schematic](Docs/precadsr.pdf) * PCB layout: [front](Docs/precadsr_layout_front.pdf), [back](Docs/precadsr_layout_back.pdf) * [BOM](Docs/precadsr_bom.md) * [Build notes](Docs/build.md) How to use 7.5mm holes, not 6mm - alpha pots - 9.8mm, +2mm - rotary - 11.5mm, +3.5mm -- biggest by far, maybe 12.6mm?
