BECOS FX CompIQ TWAIN Mk2 Dual Band/Stacked Compressor for Guitar and Bass

CompIQ TWAIN is a precision tool for dynamic audio processing of bass and guitar signals, which gives tremendous control over compression parameters and then some. It features adaptive auto attack & release timing presets and independent compression controls for knee, threshold, ratio, and make-up gain – on each band. It can work as a dual-band compressor/limiter with variable crossover point, or as a stacked compressor with separate controls for each analog engine – at the flick of a switch.

NOTE: Knob design and color may differ from images.

The Twain MK2 version removes both saturation engines on the dry line, which were intended to add controlled harmonic distortion for dual-band processing on MK1. Instead, it adds a multi-function switch for Feed Forward / Feed-Back compression mode for each band, or a combination of Feed-Forward for Lows and Feed-Back for Highs. It also includes a variable Side-Chain Filter with cut or boost in the control signal for both bands, an updated input preamp with ±12dB boost or cut, and a signal peak level indicator for input and output. Additionally, we offer the optional DITOS transformer-balanced DI output to send the signal to a mixing desk, recording interface, or other processor down the line.

In Feed-Forward mode, compression is fast and accurate, utilizing a pre-VCA copy of the input signal. This mode can range from subtle compression to brick-wall limiting, depending on the control settings. The newly introduced “old-school” Feed-Back compression delivers a smoother response, ideal for transparently evening out playing dynamics, using a post-VCA copy of the audio signal for dynamic processing. A combination of the two modes is available, providing compression and up to limiting for the lows (Feed Forward) and smooth compression for the highs (Feed-Back).

With the flip of a switch, the two independent engines can be stacked in series to slow down compression further, achieving a thick & gluing or fine smoothing, optical-like compression feel. This mode benefits from the variable Side-Chain Filters on both lows and highs. The Side-Chain capabilities now include a variable Lo-cut/boost filter specifically designed for bass instruments (±12dB @ 90Hz, 12dB/octave), which helps prevent premature engagement of the lows compressor. The matching variable Hi-cut/boost filter (±7dB @ 3kHz, 12dB/octave) further smooths out the compression feel for the highs. These enhancements manage optimal compression across lows, mids, and highs, delivering professional dynamics and extending the threshold range down to -50dBu when boosting their frequencies in the side-chain.

The optional DITOS board features a transformer-coupled balanced output in 1/4″ TRS format for direct recording or signal sending. It can also serve as an unbalanced floating output to another pedal or amplifier, capturing output transformer warmth. The main output is always functional.

The Twain Pro MK2 retains the highest performance 4320 THAT Analog Engine® enhanced by Burr-Brown™ FET signal conditioning throughout the circuit, rendering tight and punchy lows, and warm-ringing highs. It provides the musical response of studio quality vintage analog circuitry processing, with full controls for professional compression and limiting in a very compact format.
