I was scoping the input of each stage in an amp build,look what I found hitchhiking on my signal

[Helmholtz]

Helmholtz, trying to drive a gain stage/tone stack/gain stage with a square wave gives interesting results.

Sure, so what do you get?

I often use a square wave test signal. The response tells a lot about frequency response and stability.
The question here is if you see ringing.

If the overshoot is too large adjust tone controls for best square wave reproduction.
