Dude. I’ll assume you’re not trolling for a second. Swelchy is one of the nice people here- he never picks on people. There’s a lot of nice people here. He was just giving a suggestion because it’s two three holes. You don’t have to take that as a suggestion, though I think it’s a good one.
He didn’t know that you would consider it a “waste of time” to learn how to drill it without a provided template. I could have marked those holes faster than it’s taken me to write this post so far.
Here’s some context directly related to your questions- build docs and drill templates are not guaranteed for these PCBs. It’s one guy doing it, there’s a lot of demand, and sometimes products are released without build docs because a lot of people don’t need them to build the pedal. If a product doesn’t have build docs, and that’s a deal breaker, you can choose not to buy it.
I think this will help. It’s a drill template for the microsplit. You just need to put the one hole for the TRS cable on the other side for the DC jack, and possibly drill it a little smaller if you like.
