frequencies adjustable, that the specific process is
musically adaptive to upper bass areas as well. It’s
all about tone. The “box” of the guitar can be warmly
accented without making it thuddy. The richness of
chords can be improved. Amplified horns receive an
exhilarating reach to the lower notes. Of course, not
all instruments can benefit. We doubt whether Big
Bottom does much for a Cornet, for example. But,
you never know until you try! We have been pleas-
antly surprised many times.
Now the tech stuff again. Big Bottom starts by split-
ting the unaltered input signal to a main path and
a side chain. The side chain comprises an adjust-
able lowpass filter (Lo Tune), a frequency dependent
phase shifter, and a peak limiter. The output from
the side chain is added to the unaltered signal in an
adjustable amount set by the Lo Blend. The charac-
teristics of the phase shifter and peak limiter have
been highly refined though extensive research.
The result of this combination of processing is a
variable amount of low frequency equalization that
slides through a range of shapes and frequencies
continuously as the note is played and decays. The
