Hey all, built a Magnetron and haven’t really been enjoying it. I have been trying out different component value to get it sounding brighter, and I stumbled upon the dark rift and really love that shape knob to blend between square and triangle wave modulation. Would it be possible to add the same to the Magnetron? I believe they are both similar builds.

Probably. You have to replace R25 and R26 with a 500k pot. This would give you something similar to the Smooth control in the Trembling Loon.
That worked perfectly! Thanks for the help.

Clever!
The real question is do I mod mine or get a second.....

It was an easy mod and hassle free with mounting the extra knob, I just removed the rate led and put the knob in its place. Go for it!

I assume Lug 1 replaces R25, Lug 2 to IC2.2 non-inverting, and Lug 3 to R26?

Build another, then mod both!

One pad each from R25 and R26 will have continuity with each other. Connect one of those pads to Lug 2 on the pot. The other R25 pad will be the smooth signal and the other R26 pad will be the square wave. You can wire lugs 1 and 3 accordingly, depending on if you want square wave CW or CCW.
P.S. a 250k pot might work as well.
