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!
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 as well as the optimum
conditions for signal transfer.
The transformer output stage works in
conjunction with the pedal to provide the user
with additional tone-options and connectivity.
A custom-designed transformer sits at the
heart of the output stage. The core-size and
material have been selected to contribute
harmonics when driven by the Class-A,
transistor-based, output amplifier.
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 drums, bass and vocals.
