The Empress Effects Compressor MKII delivers studio-quality compression with advanced controls tailored for guitar and bass players seeking more than basic pedal features. Building on the success of the original Compressor, this updated version offers precision, transparency, and versatility within a compact, eye-catching blue enclosure.

Main Features

• FET compressor with fully analogue, transparent signal path
• Multi-segment metering for input level and gain reduction monitoring
• Selectable compression ratios: 2:1, 4:1, and 10:1
• Independent attack and release controls for precise dynamics shaping
• Mix knob for parallel (New York-style) compression blending
• Tilt EQ control centred at 500Hz for tone sculpting
• Sidechain input with selectable high-pass filter settings (120Hz, 240Hz, or off)
• External sidechain send and return via 3.5mm TRS jack
• True bypass switching for zero tone coloration
• Compact die-cast aluminium enclosure in stylish blue finish

Premium Transparent Compression

Experience a clean, warm compression effect that preserves your instrument’s natural tone. The FET circuit provides smooth gain reduction without digital artefacts. Choose from three ratio settings to match your playing style, then refine your sound with adjustable attack and release parameters for ultimate control.

Practical Design and Advanced Monitoring

The MKII pedal is approximately half the size of its predecessor, saving valuable space on your pedalboard. Dual multi-segment LED meters provide clear visual feedback on input and compression levels. The Mix control enables effortless parallel compression, allowing you to blend dry and compressed signals for dynamic and punchy results.

Tone Control and Enhanced Sidechain Options

Shape your tone with the innovative tilt EQ focused around 500Hz, perfect for cutting through the mix or warming your sound. The sidechain filter helps prevent unwanted low-frequency pumping by selecting 120Hz, 240Hz, or bypassing the filter altogether. For extended control, route external sidechain signals through the dedicated send and return jacks.

Frequently Asked Questions ➤ What instruments work with the Empress Compressor MKII? It is designed primarily for guitar and bass but works well with any instrument or audio source requiring high-quality compression and dynamic control. ➤ How does the tilt EQ affect my tone? The tilt EQ simultaneously boosts and cuts frequencies around 500Hz, allowing you to brighten or warm your sound for versatile tonal shaping. ➤ Can I use the external sidechain for ducking effects? Yes, the 3.5mm TRS send and return jacks let you route an external signal to trigger compression, ideal for ducking or advanced sidechain compression techniques. ➤ Is the pedal true bypass? Yes, the Compressor MKII features true bypass switching to preserve your signal integrity when the pedal is off. ➤ What power supply does the pedal require? It runs on a standard 9V DC centre-negative power supply with approximately 100mA current draw; standard pedal power adapters are compatible.
