There is not much I can say here. There are tons of information on Internet teaching how to solder. You can even find hundreds of videos on YouTube showing how to do it. It's just beyond the scope of the MegaDrum documentation. Just a few points here.
- You need some soldering skill. How much? I don't know, I just can't measure it.
- You need a reasonably good soldering iron.
- You need to understand what electronic schematics/PCBs mean. You need to understand how the electronic schematics ARE the guide on how to place/solder and connect components.
If, from your experience, you think I can add some more info here, please contact me on the forum or via e-mail. I'll add any helpful info here you will offer me.
