Studio-Grade 1176 FET Compression in the Timeless Classic Chassis

The Origin Effects Cali76 Bass Compressor Classic Brushed Aluminum Edition delivers world-class, studio-grade FET compression directly to your pedalboard, wrapped in the iconic industrial enclosure that established Origin Effects as the industry benchmark for tone-shaping. Inspired by the legendary Urei® 1176® studio outboard compressor found on generations of classic albums, this pedal utilizes an uncompromising, 100% all-analog discrete circuit pipeline to bring legendary punch, transparency, and high-definition dynamic control directly to the modern bassist.

This edition moves beyond standard utility utility boxes, acting as an elite tone-shaping tool. It excels at smoothing out transient peaks, maximizing clean sustain, and imparting an expensive, "produced" character to your bass lines, regardless of your playing style or genre.

Advanced Dynamic Control and High-Pass Sidechain Filtering

Unlike standard guitar compressors that swallow your low-end notes, the Cali76 Bass Compressor features a full array of studio-style controls, highlighted by a dedicated HPF (High-Pass Filter) knob. This control applies a variable filter to the internal sidechain circuit (ranging from 20Hz up to 350Hz), preventing heavy low-frequency energy from triggering the compression path prematurely. This allows the lower strings to retain their natural, explosive dynamic power while the pedal focuses on compressing and tightening up the mid-range and top-end transients of your pick or pop attack.

The fully variable Attack, Release, and Ratio knobs allow you to seamlessly shift from transparent peak limiting to a percussive, lively smash. Meanwhile, the integrated Dry blend knob unlocks true parallel compression, letting you mix your uncompressed direct bass signal back in with the squashed signal to retain transient attack and organic touch response.

Unrivaled Headroom and Real-Time Visual Monitoring

Engineered for low noise and superior audio fidelity, the Cali76 Bass Compressor converts a standard 9VDC power source internally up to an ultra-high 24V rail. This significant increase in clean internal voltage gives the pedal immense headroom, enabling it to process high-output active preamps, five-string bass transients, or line-level studio track gear without clipping. To remove any guesswork on stage or in the control room, a responsive, front-facing 10-LED gain reduction meter bar graph provides absolute real-time visual tracking of exactly how much—and how fast—your signal is being compressed.

Product Intelligence & Core Attributes

• Best For: Pristine studio tracking, live mix-cutting performance, high-definition slap bass clarity, and transparent dynamic leveling.
• Tone Profile: Ultra-transparent, high-fidelity, punchy, uncolored, and pristine.
• Compared To: Original large-format Cali76, Empress Bass Compressor, MXR M87 Bass Compressor.
• Country of Origin: Designed and hand-assembled in England.

Sanctuary Expert Note: The Classic Brushed Aluminum Cali76 is the purest expression of studio compression on a pedalboard. If you want the legendary punch and transient control of an 1176 rack unit without coloring the inherent voice of your boutique bass and high-end rig, this is the exact version you put on your board.
