The Cali76 is a premium-quality, 1960s-
style FET compressor, inspired by the
legendary Urei 1176. The idea behind this
design was to bring the sonic properties of
this revered studio-classic into the scope of
the average guitar-geek…
The topology of the design was kept true to
the original, whilst the actual circuitry was
carefully condensed. In this way it has been
possible to retain the much-loved dynamic-
response of the original, whilst at the same
time permitting a smaller, more stage-
friendly format!
Excluding the VU meter, the circuitry is
wholly transistor-based (otherwise known
as "discrete"). Well designed transistor-
circuits, in contrast to IC-based designs,
generate fewer harsh distortion artefacts.
In addition, subtle harmonics are created
which can positively-enhance tone.
Origin have also included a studio-grade
1960s-style discrete preamp, to work as an
interface between your guitar and the
compressor. The preamp provides gain and
also creates the optimum conditions for
signal transfer.
The pedal can be powered by a 9V battery
or from a 9V to 18V DC power supply. A
higher voltage supply will increase the
dynamic-range/headroom of the unit…
The Cali76 is a great performance tool, but
is by by no means limited to this task.
Recording guitarists will find the unit
highly useful for post-processing recorded
drums, bass and vocals. The Cali76 will
tame rogue dynamics and liven up flat-
sounding mixes... Best of all it will impart
a strong analogue footprint on otherwise
sterile, digitally-recorded tracks.
