Parentheses Fuzz issues.

[Diatrive]

Hello all,
I just built one of these and am having some problems.

1. The pass through works fine so I assume the wiring is ok.

Assuming these are on one at a time:
2. The boost works fine and the LED lights up.
3. The octave doesn't change the sound at all but the LED lights up.

4.The boost and the octave can be on at the same time.
The boost still works and the octave has no effect but both are clean tones.

5. If you hit the RAT switch all sound stops and the LED lights up.
No matter whether the boost and octave are on or off in any combination.

6. While the silent RAT is engaged and the volume knob is turned you can hear some static that increases/decreases when the knob is turned.

Basically the RAT portion of the pedal doesn't work at all and cuts all guitar and the octave doesn't change anything.

What op amp are you using?

Lm308 but I've swapped for another known working one and an op07 and same issue. Here is exactly what mine is doing

Start a new thread and provide some pictures in the top post. I can't see much from the dark video. Out of curiosity (this seems to be a bigger/different problem than IC oscillation), where did you source your ICs?

I would clean up your wiring on that build for sure. A few rats I’ve made have had that same sound but the issue stopped after I trimmed the leads and used shielded wire on the in/outs.

Will do I was just searching forums at lunch so figured I'd ask
