I found an old Little big muff pi (https://www.ehx.com/forums/viewthread/1241/)
but I noticed that some of the components of the electronic device were missing
If someone could send me a detailed picture of all the electronics, i would be able to find and weld the missing components.
How about some pics showing the areas where you think parts are missing?
As you can see there are empty holes, this lets me think that there are missing components.
There is one hole hidden behind a wire.
Thanks for the help.
Every hole is welded but sometimes there is nothing in it (Ther’s a red circle on every empty hole)
I rotated this picture to be able to overlay the two pictures
The holes along the bottom are where the pots would be connected if the board was used in a Big Muff. The others are just extras and there are no parts missing that I can see.
I’v got one more question
The following picture is a jack socket but i belive that there should be two wires as on the other socket (not present on this picture)
This is the detail that bought me to belive that components weren’t here.
If what I say is true, could you show me where to put the missing wire on the board.
The (non)missing wire is a ground wire, which it doesn’t need because it grounds through the chassis to the input jack ground.
Yea it all looks fine to me too!
Its an opamp big muff you have there too, one of the best IMO. you can adjust the tone and sustain by swapping/removing resistors of certain values if it dont sound quite right.
Yeah but here it doesn’t sound at all
Perhaps it is because of its old age and some components could now be out of use.
Where could I repair my pedal (I’m not sure that a normal music shop keeper would be able to repair it)
