Crazy Tube Circuits Golden Ratio vs Keeley GC-2

The Crazy Tube Circuits Golden Ratio and the Keeley GC-2 are both pedals. The Keeley GC-2 leans transparent and smooth.

Similarity
citedBlended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.

Description

The Crazy Tube Circuits Golden Ratio (Phi) is a dual-engine compressor pedal featuring separate FET and optical compression circuits in one enclosure with a switch to select between them. The FET engine delivers crisp, punchy compression while the optical circuit provides warm, fluid compression. The pedal essentially delivers two distinct compressor voices in one unit. Built in Greece by Crazy Tube Circuits with boutique quality components.

The Keeley GC-2 Limiting Amplifier is a studio-grade opto-optical compressor pedal from Keeley Electronics (Edmond, Oklahoma), modeled after the LA-2A style optical compressor limiting amplifier for smooth, transparent gain control and dynamic limiting. The GC-2 provides studio-quality opto compression with Threshold, Output, and Blend controls for natural, musical dynamic control at Keeley boutique quality.
