why do tubes have a treble lost ??? when you hook up a distrition pedal but when the guitar clean or acustic nice balance of treble and bass

When a distorted wave flattens against either rail,
or reaches maximum slew rate, information is lost.

I'll make a guess that the distortion generating mechanism makes lots of annoying high harmonics that they needed to get rid of with a low pass filter.

Maybe they used a spoke, I mean, a spike shaver circuit (intentionally limited slew rate) to get rid of glitches too.

When tubes are used properly you can get plenty of treble, bass, and
distortion all at the same time ;-) No pedal needed...

Since VTs are naturally Hi-Z devices, you can sometimes run into problems with excessive Cmiller when using high gain triodes (12AX7, 6SL7, 6SF5, etc.) that cause a premature roll off.
