Why won't the Spirit Box (Ghost Echo) oscillate?

[nate433]

Hey ya'll. I was building a ghost echo when I wanted to try a simple mod I've seen elsewhere.

Here it talks about using the unused Belton Brick output (Pin 5) and connecting it to the input for oscillation.

I assumed you would be able to do the same with the Spirit Box, since it also has an unused output pin (Pin 6). Nothing happened though? So is there something else at play here or is it something as simple as you can do it if the pedal used Pin 6 for the main output but not Pin 5?

Thanks!

Maybe you need to have a bunch of gain after it like that project?

There already is a feedback section in the Ghost Echo. If yours doesnt oscillate when you crank the « dwell » knob, try and reduce R8 (22k)
