SOLVED Duocast Hi/Low Gain channel

[u439857293874]

Hello, I put together this Duocast build and the regular channel works but the Hi/Low gain channel only passes clean audio. I traced it with the sound probe and I can't find where the problem is because I'm getting sound through the whole pedal. Looks like the Level 2 trim pot is the last in the chain according to the schematic. I'm getting the right audio up to the end of the chain so maybe its something on the 3DPT switch? Not sure why this is happening.

Check all the Footswitch Pads on the RIGHT Main Board for Solder bridging.
Check For Continuity on Matching Colours.
Green Circles are GROUND.

This is the same layout as I listed 3 hrs ago but there was a stray circle near C4 that was removed!
Trying to determine that Level 2 traces are not damaged.

Any Updates on this?

Check for Continuity.

I'm trying to get this working, have you given up?
We can use jumper wires on the underside if you have damaged traces!

Hi, I haven't given up! Thanks for following up. So it appears that we finally have something! I'm not getting continuity on the two blue spots. Level 2 center and the blue circle on the right foot switch.

Should I connect a jumper between the two blue points since im not getting continuity there?

I think we are close! I just connected these two spots with clips, turned the pedal on and it seems like its working!! When I engage the hi/low channel it gives me the level I set in Level 2 then when I disengage it goes back the to the Level 1 volume!

I think we can call this solved! I just boxed it up, put it on my board and its fully working!

My thumbs up was 1.15 am this morning.
I just woke up, it's 7.30 am in Western Australia now.
Glad to see that it fired up.
The High trimmer controls how much Gain you want on Volume 2.
Low trimmer for extra gain on Volume 1.
