Boss CS-3 makes a fuzzy noise when engaged

[matthewjhawkins]

I have a Boss CS3 compression and sustain pedal. I have owned it for a while, and all of a sudden it has now become very noisy. I took it apart, and all solders appear to be intact.

It only fuzzes when the pedal is engaged. Any hints?

What is your level of technical skills?
- can you obtain and use a voltmeter?
- ... ohmmeter?
- can you read a schematic?
- can you solder reliably on PCBs like the one in the unit?

I am pretty technical. I have worked on computers a decent amount, and done some soldering.

I dont have access to a multimeter, but I can get one.

I can read some schematics, I have a semester of electrical physics under my bealt, a bit rusty, but I can figure it out most likely.

my soldering seems decent, it looks similiar to the existing solders.
