Title: Afterlife - weird knob behavior
Post by: Willybomb on February 15, 2016, 09:05:41 AM
Gudday all, just populated an Afterlife, no substitutions in the build.  It's acting pretty oddly though and if someone can help me out I'd appreciate it.

The sustain knob crackles when turned, and;
The volume knob is pretty quiet till until it's nearly fully clockwise, then there's a couple of hours of pretty loud, but the last half hour or so goes back to silence at the full clockwise turn of the knob.

I'm not using the breakoff knob board, but you'll see that in the pics.  I read the schematic and the layout and wired the pots as I understood it.  I recently did an Egghead and did the same, and that worked.

If you have any ideas, please let me know.

Thanks,
Willy.

I had a similar issue because of not using the daughterboard. I had wired the leads straght as I had assumed to be right but in fact they needed to be connected like this:

Thanks. I had to go 5->pin3, 6->pin2, 7->pin1 on the volume to get the clockwise volume increase.

On the sus control I went 1->pin1, 2->pin2, and connected pin2-->pin3.
