Re: Adding Tone Stack Caused Whistle?

Would the oscillation be caused by the pretty basic filtering or would
there probably be more to it than that?

Could be design, layout, the way you hold your lips...

Suppose I should ask if this
sort of oscillation will cause any harm to any components.

Yes... your ears. Also causes funky wolf-tones even when
it's not happening... like bad noise on volume peaks (down-strokes).


If the whistle originates in the second stage then gets leaked into
the first stage which sends it back to the second stage etc. I can see
what the problem is.

It's the two stages working together... the second stage amplifies
a high frequency, that makes it back into the first stage, then round-
and -round we go.

Sorry about all the questions. This is interesting stuff for a
beginner like me. Now I know what to look up, I'll see what I can find
in the books I have.

Many thanks for the help, Green

GL! If something makes it worse, do the opposite...
