NUX Komp Core Deluxe MKII
The NUX Komp Core Deluxe MKII is a compact, fully analogue compressor pedal designed for guitar and bass players seeking precise dynamic control. It features a versatile five-knob interface and a dedicated attack switch to maintain musicality across various pickup types.

Overview
The NUX Komp Core Deluxe MKII is a multi-function analogue compression pedal designed to provide clear, controlled sustain and dynamic management. Positioned as a versatile tool for both guitarists and bassists, the unit emphasises tweakability within a standard compact pedal format. It is intended to offer professional-grade compression features, such as parallel processing and input gain management, at an accessible price point.
Key Features and Controls
The pedal distinguishes itself through a comprehensive control set that exceeds the standard two-knob compressor design:
- Blend Control: This allows users to mix the original dry signal with the compressed signal, facilitating 'parallel compression' to preserve natural note attack.
- Clip Knob: Manages the input gain to ensure that 'hot' signals from active pickups or high-output humbuckers do not cause unwanted clipping or distortion.
- Attack Switch: A two-way toggle that allows users to select between 'Fast' and 'Slow' attack times, tailoring the pedal's response to different playing styles or instrument types.
- Five-Knob Interface: Provides independent control over essential parameters to fine-tune the compression curve.

Sonic Character
As a fully analogue device, the Komp Core Deluxe MKII is designed to maintain the transparency of the host instrument. The inclusion of the Blend knob is critical to its sound, as it prevents the 'squashed' or 'lifeless' feel often associated with heavy compression. By allowing the dry transients to pass through while the sustain is increased by the compressor circuit, the pedal achieves a balance of increased thickness and rhythmic clarity.
Applications and Compatibility
The MKII is suitable for a wide range of musical applications. Its adjustable attack settings make it equally effective for the 'snappy' country-style compression required for single-coil pickups and the smoother, more sustained requirements of humbucker-equipped guitars. For bassists, the Clip and Blend controls are particularly useful for maintaining low-end definition without losing the punch of the initial string strike.
Comparison to Alternatives
When compared to entry-level compressors like the Behringer UC200, the NUX Komp Core Deluxe MKII offers significantly more control over the signal path via the Blend and Clip functions. While standard utility pedals like the Boss NS-2 focus on noise reduction, the NUX focuses on tonal shaping. It competes with higher-end boutique compressors by offering parallel compression—a feature often missing from classic designs like the standard Big Muff or basic flanger circuits like the Fender Hammertone series.

Frequently asked questions
- Is the NUX Komp Core Deluxe MKII analogue or digital?
- The pedal features a fully analogue circuit design, ensuring a traditional response and signal path for the compressed audio.
- Can this pedal be used with a bass guitar?
- Yes, it is designed for use with both guitar and bass setups, providing clear and controlled compression for both frequency ranges.
- What does the Blend knob do?
- The Blend knob allows you to mix your dry, uncompressed signal with the compressed signal, helping to maintain natural dynamics and attack.
- What is the purpose of the Clip knob?
- The Clip knob manages the input gain of the pedal. This helps to prevent unwanted distortion when using high-output or 'hot' instrument signals.
- What does the Attack switch toggle between?
- The switch toggles between 'Fast' and 'Slow' attack times. This allows the player to choose how quickly the compressor reacts to their picking.
- Which attack setting is best for humbuckers?
- While it depends on the desired sound, the toggle switch is specifically included to allow players to adjust the response to suit humbuckers or single-coils.
- Does the pedal have a compact footprint?
- Yes, the MKII is built to be pedalboard-friendly with a compact chassis that fits easily into standard signal chains.
- What is the typical price for this pedal?
- The NUX Komp Core Deluxe MKII typically retails for approximately £60.
- Does this pedal include a built-in noise gate?
- No, it is a dedicated compressor. For noise suppression, a specific pedal like the Boss NS-2 would be required in the signal chain.
- How many control knobs does the pedal have?
- The pedal features five independent control knobs for precise tone and compression shaping.
- Can I get a completely 'squashed' sound with this pedal?
- Yes, by adjusting the five knobs and the blend control, you can achieve anything from subtle levelling to heavy compression.
- Is the MKII version different from the original Komp Core?
- The MKII is an updated version that features the five-knob layout and flexible attack switch for enhanced control compared to simpler models.
