Boost Comp
Tech 21’s dual-channel Boost
Comp is practically a fullyfeatured,
all-analog,
FET
preamp, being outfitted with
not only compression and clean
boost, but also considerable
powers of equalization. The
comp-EQ section and the boost
section are independent, and
each channel has a dedicated
footswitch. The boost comes
last in the signal chain, and
provides 21 decibels of clean,
unaffected wallop that, when
combined with the compression
and EQ, can transform a tube
amplifier without robbing it of
dynamics and personality. The
Boost Comp’s compression
circuitry is the main attraction
though, and it is lovely indeed.
It can function as a subtle,
transparent tone enhancer or a
ruthless dynamic vise, all without burying the guitar sound in goop or detracting
from its natural tonal qualities. The Tone and Presence controls are thoughtfully
designed, with the presence functioning as a pre-compression attack enhancer,
while Tone can cut or boost the signal substantially after it leaves the compressor.
This is superb for alleviating that dark tonal quality that heavy compression can
sometimes imbue to an audio signal. The Tech 21 Boost Comp is as high quality a
compressor as can be found in pedal form, and its other impressive functions are
just icing on the cake.
