Hi Rob.

I do agree with Borislav that the volume adjustment graph he posted shows what I hear when adjusting the volume on my empeg: The volume adjustment is not linear in terms of dB nor in terms of human audibility. If it where, the graph Borislav posted would either be flat (linear on dB) or had a log/exp scale (I just can´t concentrate enough right now to tell which one).
The human audibility is roughly a doubling of the "felt / heard" volume on an advancement of 10dB. So the volume I hear (y) is about 1/2^(-/10), or the volume setting for any given factor y is about -ld(1/y)*10.
As we should all know, ld (log(x)/log(2)) is a continuously ascending function, so Borislavs graph should also have some continuity, no changes from ascending to descending and back.
