Bring out yer Diptrace

I mean mechanical components all on the same board.

I understand the allure but it’s a gamble tje more components you board mount.

The one concession I'm making in terms of reliability is the 3pdt switch. I sourced good quality switches for this, but in the future I'd like to forego it and work in a relay bypass. With the 3pdt a bad switch could nerf the whole board, but this is a prototype so I'm ok using it.

I've used the cheaper Chinese ones in all my pedals up until now and I've only had 3 (out of at least 100) go bad, but still I didn't want to permanent mount one of those into the board.

In the next round I'm probably going to use TS neutrik jacks which don't have the pads for the ring terminal, which allow better trace routing underneath them. When I get to building this board up I'm going to check out how much vertical space there is between the pots and the jacks and see if I can squeeze them together better to make more room for relay bypass components.

I'm also going to see if there is room to put anything on the bottom of the board. I have a trim pot for the LED brightness there now as an experiment. If it doesn't fit I can install a jumper instead, but I'd like to be able to squeeze the relay itself on the bottom side between the audio jacks. Fingers crossed.

This is my inspo


They used a daughterboard for the pots whereas I used long leg pots. In the MXR pedals I've taken apart, the side jacks' holes have been extended down to the base of the enclosure, making the hole into a tombstone shape so the pedal can be assembled with the nuts attached to the jacks. Seeing this gives me confidence about my design as it's meant to be assembled the same way.
