Obviously, lots of pure, undistorted output

rom a lar

e amplifi er is better than a distorted
signal
f
rom a small ampli
fi
er stretched beyond
its capacit
y
. The si
g
nal from a distortin
g
(clip-
ping) ampli
fi
er contains much more high-
f
requency information than an undistorted
si
g
nal, and there
f
ore puts a heav

It is worth notin

that when the tone controls

On a
