GssL 20th Anniversary edition

Second; Your change wth +12V to gain, you are referring to the connector "GAIN" in Side Chain Sum left of the Threshold ?
Old Wiring is Gain between -12V & +12V, new wiring is unconnect Pin 1 and using Pin 2+3 and Pin 1 is tied to ground on the Potentiometer (not the main board)

I am trying to help those who aren't as much experienced.

Did you get this sorted out? I completely missed this! I have all cables to the connector on the board.

1. Your soldering can be interpreted in two ways.

Either, you started out really descent, and got impatient, or

You started out a little rough, then got better.

There is a clear difference across the board, and a lot of suspect cold soldering joints, but either you need to just be patient, or keep going with what you learned

I would reflow them. Use a little tin on your tip to get it flowing, and make sure you are heating both the pad and the component terminal.

2. The threshold needs adjustment on a resistor for the 10K pot, relative to using a 50K in the standard GssL. I may have forgotten I just did that on the prototype, and didn't correct it in the file. I cant get to the computer I have the file on now, but whats the voltage on pin 2 fully ccw and fully cw?

Yes I saw that to when I turned the board around today it was I got impatient I believe I will measure pin2 tomorrow and reflow those wacky spots. And looking forward to which resistor that maybe have to change.

Its not a good idea to risk introducing another error variable before we have sorted what is in front of us - at least since this is a non-critical issue for basic operations.

Doing the mod will change your make-up gain from going both positve and negative to going only positive.

I hear you Gustav. On a later step this one.
