Introducing the Cali76 Stacked Compressor:

The Cali76 Stacked Compressor is a dual-stage compressor pedal, using two compressor circuits cascaded in series for the ultimate compressed guitar tone. Representing the latest evolution of our world-renowned Cali76 circuit, the Cali76 Stacked Compressor gives you super-squashed cleans, singing slide tones, and endlessly sustaining leads without having to reach for an overdrive pedal.
Inspired by the iconic Urei® 1176® , this pedal combines studio-grade ﬁdelity and control with enough compression to totally transform your tone. The Cali76 Stacked Compressor encourages you to use compression as a creative effiect, not just a tool.

Key Features:

Dual-stage design for maximum compression

All-analogue signal path
Independent controls for each stage

Huge range of compressed tones from subtle to over-the-top
Dry level control for parallel compression

Individual LED gain reduction indicators for each compressor
Voltage increased internally to 24V for high headroom

High-quality buffered bypass
Premium components throughout

Designed and built in England

Connecting the Cali76 Stacked Compressor:

9VDC: Connect a 9VDC 2.1mm centre-negative mains power adaptor (minimum 200mA). Voltage is increased internally for additional headroom.
NOTICE!
Damage to device if powered incorrectly!
This product is designed to be powered from a 9VDC, >200mA power supply with 2.1mm centre-negative barrel connector. Use of an incorrectly rated power supply could result in damage to the pedal and the power supply.
INSTR: Connect to your guitar or other instrument.
AMP: Connect to your ampliﬁer or other e ects pedals.

Controls:

IN: This control sets the level into the ﬁrst compression stage. Higher settings result in more compression, as more signal is pushed over the ﬁxed threshold. The LED on the right will indicate when the ﬁrst stage is compressing. Increasing the IN control will also make the signal louder, so this should be balanced with the THRU and OUT controls.
NOTE: Each compression stage has a ﬁxed ratio of 4:1
OUT: This control determines the level of the compressed signal present at the pedal’s output. This control may need to be increased or decreased when adjusting the IN and THRU knobs. For most predictable results, compare your compressed signal to the bypass tone and adjust the OUT knob so that the levels match.
DRY: This control varies the amount of dry, uncompressed signal present at the pedal’s output, mixing the dry signal in parallel with the compressed signal. Adding some uncompressed signal in parallel can restore some natural dynamics and clarity to heavily compressed sounds. Unity gain can be found at approximately 2 o’clock on the DRY knob, while turning this control fully clockwise will boost the signal by 9dB.
NOTE: The DRY control and OUT control are separate level controls, so you will need to decrease the OUT control as you increase the DRY control to maintain the same overall volume.
ATT/REL 1: This control sets the attack and release characteristics of the ﬁrst compression stage. Fully counterclockwise, the compressor has a fast attack and slow release, reducing pick attack and increasing sustain for smooth, even dynamics. Turned fully clockwise, this controls sets a slow attack and fast release. Pick attack will be exaggerated and the compressor can recover between notes, creating a percussive and lively response.
THRU: This control sets the level of the signal fed from the output of the ﬁrst compression stage to the input of the second compression stage. This determines how much compression is applied by the second compression stage. Turn clockwise to get more compression from the second stage. For more subtle, singlestage compression sounds, turn the THRU knob fully counterclockwise.
ATT/REL 2: This control sets the attack and release characteristics of the second compression stage. Just like the ATT/REL 1 knob (above), it ranges from a fast attack and slow release (counterclockwise) to a slow attack and fast release (clockwise).

ON / OFF Operation:

Bypass Switch: This switch toggles the pedal on and off. The Cali76 Stacked Compressor uses buffered bypass and electronic switching for low-noise operation. When powered up, the pedal will automatically default to being switched on. This is so it can easily be used with switching systems and rack systems, where pedals need to be left active and may be inaccessible.
NOTE: It is good practice to always turn on your pedalboard ﬁrst, before turning your amp on or connecting any DI outputs, as some pedals can produce a “pop” noise when powered on.

Noise and Signal Chain Placement:

The Cali76 Stacked Compressor is capable of extreme levels of compression, so we recommend using it at the start of your signal chain. Only pedals that don’t work after buers should go before it, such as vintage fuzz or wah.
Compressors, by their very nature, increase the level of quiet signals and decrease the level of loud signals. So, any background noise coming from before the compressor will be ampliﬁed signiﬁcantly. As such, even a lowgain overdrive could seem noisy if used before the Cali76 Stacked Compressor. And, if you are using a vintage fuzz before your Cali76 Stacked Compressor, it is probably best to turn the compressor off when you turn your fuzz on!
Compressors will also increase the level of hum picked up by single coil pickups. This can be reduced by using more subtle compression settings.

Line Level Signals:

The Cali76 Stacked Compressor can also be used with line level signals. The 9V input voltage is increased internally to 24V, resulting in impressive headroom. This means that the Cali76 Stacked Compressor can be used with keyboards, drum machines and as studio outboard. It can be connected in the insert of a mixing console or used for re-amping tracks in the studio.
Although the pedal has plenty of headroom for dealing with higher signal levels, the circuitry is still primarily designed for use with guitar signals, so it may be necessary to lower the IN control to accommodate line level signals and avoid excessive compression. This will ensure that the right amount of signal is exceeding the ﬁxed threshold, and this can be monitored using the LED gain reduction meters.

Routing Diagram:

The diagram below shows the signal routing within the Cali76 Stacked Compressor.

Sample Settings:

STACKED COMPRESSORS
Two compressors in one pedal! Stage 1 is set for a slow ATTACK and fast RELEASE, providing a snappy, funky tone. Stage 2 is dialled in for fast ATTACK and slow RELEASE, fattening up your whole signal and increasing prominence in the mix.CLEAN OVERDRIVE
This setting gives you all the feel of an overdriven tone without the distortion! Perfect for clean lead playing and slide guitar, this endlessly sustaining tone is smooth and responsive. Your clean tone takes centre stage.PARALLEL COMPRESSION
Get the best of both worlds – heavy compression and natural dynamics. Turn up the DRY knob to add dry signal in parallel with your compressed tone. Pick attack and articulation from the dry signal balance out the fat sustaining tone of two compressors in series.
