SOLVED Mach 1 not working

[taita87]

Hello can someone tell me if this build is OK or there's something obviously wrong in the build?
The led is working but when I plug in the cables I ear nothing from the cabinet, no signal at all.

I have to admit that in the first place I plugged a 9v battery with wrong polarity, maybe I broke something with that first attempt, or maybe there something macroscopically wrong in the soldering

Uhm... I tried to re-solder the 4pin joint, reassembled and now I'm reading
1- 4.40
2- 4.45
3- 2.60
4- 0
5- 4.36
6- 4.40
7- 4.48
8- 7.90

I would suggest two things now, first is a reflow of your joints. This will hopefully ensure a good connections. Some of then look like their cold or there's not enough solder. Secondly I would also start to look at your foot switch wiring. You can check continuity if you want before trying to replace anything. Make sure you getting a good connection between the pin and the board (not the breakout board) this will give you an idea if you have a broken wire or if there's a solder issue somewhere. Good new is you have bypass so that's one step closer

It works the ground wire on the switch socket had no continuity, I just re soldered it!
