I don't want to lose the functionality of the latch/unlatch but I also want to be able to independently turn on/off the effect with a separate LED.

I've basically accomplished this, but I don't know if TB can be achieved.

I know this post is super necro...I'm rehousing a UV300 and cant get the TB switching to work right.

I am having an issue with the I/O pinout....

What exactly is your issue here? In and output?

Identify the tip connectors from the jacks on the PCB...

Most Behringer pedals have a switched input. So there are 2 active input pads. I am having a hard time to TB the pedal. I've settled on putting a switched input. I am using the original switch location for a momentary switch only with another 3pdt for a bypass.

how did you rewire the switches?

*SOLVED*

My mind always goes to the worst case scenario when I troubleshoot, thanks for everyone's help....it was indeed the input jack...lol.

I'm using the jacks that came with the fx-25...I've never used ones like this before. I believe they are wired correctly but maybe I've botched this....

I'm not even getting pass through sound...

I went through all the joints and I couldnt find any shorts.

I guess its time to test every component.....

Here is the underside

I've tested the ICs and I'm getting the right voltage. Tested for input/output continuity and it all checked out. Led lights up.

No sound....Ive been staring at the build for a day and a half and I think maybe if some other people take a look something else might come up.

perfect on the second link, thanks bud!

Is there a way to wire a battery into this circuit?
