Title: Demeter TRM1 Question
Post by: burnt fingers on October 24, 2021, 06:45:04 PM
Apologies in advance if this is in the wrong place...

So I have one of these and there is something wonky about it....working on figuring that out.

In the mean time, does anyone else have one of the 'latest' versions of this pedal and if so, does this look weird to you?

Looks like one of the legs from the B500k has gone and to the right of where that leg should be, seems to be a partial hole with solder.

On the back of the board, this exists....ie where the partial hole was/is...

I am guessing at some stage this had been rehoused into a smaller enclosure before being returned to a standard one...ie two top bits now angled...

I am intrigued if someone could post a pic of theirs if they have, wondering if this has been ruined?

Thanks in advance.

I know nothing BUT, willing to learn  ;D

Thankfully, It wasn't me who did this.

Looking at the schematic, that leg doesn't go anywhere or do anything, unfortunately.

Seems to me that this pin of pot 500k is blind and it doesn't matter if it is in pcb or not. But there are another versions at web, with different pcb. I saw them but it seems to me that it is almost the same size.

Okay....Interesting.

I have the same web schematic.

I will go through the audio path and see what I can find.

Appreciate it  :)
