CMOS Distortion bread board layout

A different way to present a design.  This is how it is laid out on the bread board.  It squeals at me when I try to set the gain too high while laying on top of the Valve Jr.

Every time I've played with CMOS for dirt, it's squealed at full blast on the breadboard but is fine once soldered together and boxed.

any chance of a soundclip?...i have a few of those in my bits box......

This has a lot of gain before it starts squealing and it is fairly quiet, at least at low volumes in an apartment.

I have not technologically advanced enough to provide clips.  Sorry.  It is pretty squishy with lots of compression and sustain and the tone circuits allow for lots of variation with different values.  Since the Valve Jr. doesn't have tone controls, it is all done with the distortion.  Smooth, Sweet, Glorious.

Try a 22n cap off the V+ pin to ground,paralleled with a 220uf cap this removed all oscillation for me.
And allowed it to run at lower voltages without squealing too.
