I haven't built the full size Low Tide only the mini but, this looks consistant with other Low Tide builds I've seen on here in terms of footswitch and PCB spacing. I haven't noticed anyone using header pins to connect the two. The builds I've seen, people are using something like the scrap legs cut off of components soldered to their board to connect the switch breakout board and the component PCB.
Here's two examples found in the build reports section:
Another Low Tide, but I used a 470p for C27 to increase the delay time for some wider pitch shifts, and a little less subtlety overall.
There's also a 2SK30 in q1, and it's not a huge difference, but is less gainy than the j201s I'd normally use in this spot
It's a PedalPCB board, so you already know that shit tight. You like wobbles? Build one, yo
It would be comical if on your earlier build you drilled the holes incorrectly and were able to use header pins, but on this build you drilled them correctly and were now questioning it. haha
