How loud your amp will go on a clean setting before the tubes begin saturating and distorting.

Its volume that you dont use. for a clean channel you need more headroom so you tubes dont saturate and your tone will distort. Tubes only saturate at high volumes so you need the headroom to stay below saturation.


or


its when you walk through the door and dont hit your head because the doorframe has enough headroom for you to get through without ducking.

Think of it in a literal sense. The headroom of an overpass on a road.

This headroom may be fixed at 10 feet just as an amp's headroom is fixd at 10 watts.

Cars (or low level signals) can pass undeerneath this headroom limit very easilly. But when you try to fit a 12 foot tall truck through ( a loud signal) the truck will come out the other side damaged or distorted.

An amp will do the same thing. Any part of the signal that is too high for this headroom limit will be cut off. And the signal that then comes out of the amp will be cut off an distorted.
It's not a nice sound and can even kill your speakers.


Amp'd's comment above about the doorway height is actually more correct than he may have intended.
