So many other places could learn a lot from this place, attitude-wise etc!

Happy to have landed here!

Okay....Interesting.

I have the same web schematic.

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

Appreciate it  :)

Mystery solved.....WOW!

New pot needs ordering!

;D

Thankfully, It wasn't me who did this.

General Questions / Demeter TRM1 Question
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

VERY new myself....

This forum rocks in so many ways, the MOST helpful place ever as far as I am concerned.

Enjoy!

This arrived and went together pretty easily...

Will be probing and looking at stuff tomorrow!!!

One working, one not....Armed with lots of ace and very helpful info from Mr JL, I will go through the audio signal path this weekend on the one that is 'thumbing it's nose at me'...once I have built myself an audio probe/tried the breakout box hack as suggested by Mr JL  ;)

Also decided to order one of these bad boys, seeing as I do not have a looper or an audio generator.

Back of the board...I thought I had been very careful BUT, I am guessing the initial suspect has to be something bridged?

I will try running a knife down in-between each copper rail.

NOT disheartened, just scratching my head a bit  :)

Appreciate any help at this point.

Sadly, this passes signal when in bypass mode and does naff-all else when the effect is engaged.

Can anyone see anything that I've obviously done wrong?

#10
Based on the assumption being correct re the potentiometer being viewed from the back of the pot, I have wired it like this.

#11
This is what I believe to be true....I went back and looked through a load of different diagrams, I can see how I got confused on some  :)

Okay....I am assuming the original schematic I am looking at shows a potentiometer mounted to the box and therefore, I am assuming the lugs are 3, 2 and 1 from top to bottom :)

HOPEFULLY that is correct.
#12
Guess I am not explaining this very well....will have a think and ask the question in a different way.
#13
Guess that was my question....In the ORIGINAL schematic provided, I am assuming that is the view from below....how do you know for sure? OR is the assumption that all pots shown are 'in' the enclosure and therefore can only be viewed one way, IE from below....

I am guessing the view is from below based on the way it is drawn(that is why I numbered it the way I did) AND this reference from Beavis Audio seems to suggest the same, to my little mind. Am I wrong?

Appreciate it! This has always confused the hell out of me...pretty sure I have driven myself nuts before with this!
:-\

Okay...onto the wiring from the board and then the breakout box testing of the one knobber.

Idiot question.

Do I have the lugs numbered correctly on the potentiometer in the picture? I have always been confused with the 'view' of the potentiometer...Think it is meant to be when inside the box?

#15
Rubbish week over, new tester arrived so I can triple check all parts before soldering to the board...

Onwards towards testing a populated board with wires(I have a breakout box)  :)
