Dual-Stage 1176 FET Compression for Infinite, Clean Tone Shaping

The Origin Effects Cali76 Stacked Compressor - Brushed Aluminum Edition delivers the ultimate in dynamic control by placing two studio-grade, 1176-style FET compressors directly in series on your pedalboard. Wrapped in Origin's classic, premium brushed aluminum enclosure, this 100% all-analog, discrete Class-A pedal goes far beyond standard compression. By running the output of the first compressor directly into the input of the second, the Stacked Edition unlocks independent control over both stages, delivering touch-sensitive sustain, absolute note definition, and a compressed overdrive quality that single-stage pedals simply cannot replicate.

Heavily favored by slide players, ambient architects, and tone purists, the Cali76 Stacked Compressor acts as a master tone-shaping anchor. It smooths out tracking transients, transparently extends clean sustain for days, and injects a high-end, multi-million dollar studio console sheen into your overall signal path without coloring your core amplifier voice.

The Power of the Thru Knob: Intuitive Dual-Stage Routing

Instead of overwhelming you with two complete sets of studio controls, Origin Effects engineered an elegant, highly intuitive user interface. The magic lies in the gold Thru control knob. The In knob sets the input gain for the first compression stage, while the Thru knob determines how much of that signal is pushed into the second compression stage. Paired with independent Attack/Release controls (optimized as combined Attack/Release parameters for each stage via the Att/Rel 1 and Att/Rel 2 knobs), you can seamlessly adjust from subtle, transparent peak-limiting to thick, low-gain squashed saturation perfect for complex clean lines or soaring slide leads.

Massive 24V Internal Headroom and Interactive LED Metering

To preserve pristine signal integrity and accommodate high-output instruments, the Cali76 Stacked Compressor accepts a standard 9VDC power input and internally converts it to a massive 24V operating rail. This ultra-high internal headroom guarantees entirely clean, transparent operation—easily handling hot humbuckers, active basses, or line-level studio inputs without clipping. For instant visual feedback on dark stages, the pedal features a dual-color LED metering system that tracks both compression stages simultaneously, ensuring you always know exactly how the FET circuits are reacting to your pick attack.

Product Intelligence & Core Attributes

• Best For: Soaring slide guitar tracking, clean ambient soundscapes, fingerstyle picking definition, studio tracking sessions, and high-end pedalboard architectures.
• Tone Profile: Infinite sustain, rich, articulate, punchy, transparent, and beautifully saturated.
• Compared To: Dual outboard Urei® 1176® units in series, classic Lowell George slide tones, standard single-stage Cali76 FET.
• Country of Origin: Designed and hand-assembled in England.

Sanctuary Expert Note: If you find a standard compressor doesn't give you quite enough sustain for slide work or clean melodic lines without getting noisy, the Stacked version is the absolute gold standard. It lets you cascade the compression gently across two stages, giving you massive, singing sustain while keeping your natural note attack clean and transparent.
