Crazy Tube Circuits Golden Ratio Phi V2 Compressor

φ (Phi) has been updated to include 3 separate compressor circuits at a flip of a toggle switch.

An internal smart switching circuit lets you decide which type of compression works best for you featuring a wide range of compression ratio from 1:1 to 20:1. Each all-analog circuit is totally independent and has its own voice with different compression characteristics, range and response of controls to suit every style. Phi will fatten up your tone even with no compression added. With the parallel compression technique of blending the compressed signal with the original – uncompressed signal, you will experience clarity and precision only found in studio recordings.

FET compressor: This is a feed-back detector / control compression circuit that relies on a FET transistor for gain reduction. It adds a distinctive color to the signal and can be set for super-fast response, but it may also introduce a bit of musical distortion.

OTA compressor: The majority of guitar compressors use this technology. Our interpretation uses a feed-forward detector circuit thus being able to “squeeze” things harder, ideal for catching fast transients and limiting. It is the most controllable circuit with punchy and direct sound.

OPTO (Optical) compressor: A hand selected photocell combined with a feed-back detector circuit offer smooth attack and release characteristics resulting in very musical and organic compression even on extreme settings. It can also be set very neutral so that you won’t be able to tell when it's on but you sure going to miss it when it's gone.

An internal switch selects between 9 or 18V DC of operation from a standard 9V DC power supply via an internal voltage multiplier. Use the 18V setting for increased headroom and enhanced compression characteristics. Features superb low-noise floor performance and full frequency response making it ideal for guitar, bass and virtually every instrument either on studio or stage.
