1. Unpack the kit double checking that you have 10x 3.5mm mono plugs and 10x AllFlesh pcbs. Using clippers (or your hands) break apart all 10 PCBs at the perforation marks and remove any remaining small tabs. (Note: I have not done that in my photo examples but this will help you in later steps to not damage your solder joints). Unscrew the mono plugs from their black plastic housings. You will need on hand safety glasses, a soldering iron, solder, clippers, and a file.
**Though I don’t love leaded solder it can be very beneficial for learning soldering and in this instance especially so because the melting point is low. Leaving the iron in contact with the solder lugs for too long or making the iron too hot can ruin the plug internals**
