Key Features of the Keeley Compressor Plus
The Keeley Compressor Plus offers a range of advanced features, including the Sustain, Level, and Tone controls, an Attack Switch for pickup optimization, and a Blend control for transparency.
3.1 Sustain Control for Dynamic Range
The Sustain control on the Keeley Compressor Plus is designed to enhance the dynamic range of your guitar signal. By adjusting this control, you can achieve a natural bloom and sustain, allowing notes to ring out with clarity and warmth. This feature is particularly useful for creating a balanced sound, ensuring that both soft and hard-played notes are evenly compressed. The sustain control works seamlessly with the compressor’s circuitry to provide a smooth, transparent compression that preserves your guitar’s natural tone.
3.2 Level Control for Output Volume
The Level control on the Keeley Compressor Plus allows you to adjust the overall output volume of your compressed signal. This ensures that your tone remains balanced and consistent, even when using compression. By fine-tuning the Level control, you can match the compressed signal to your bypassed tone or boost it slightly for added presence. This feature is essential for maintaining a seamless transition between compressed and uncompressed sounds, giving you full control over your guitar’s dynamics and output.
3.3 Tone Control for Frequency Response
The Tone control on the Keeley Compressor Plus enables precise shaping of your guitar’s frequency response. This control allows you to brighten or darken your tone, ensuring compatibility with various guitars and playing styles. By adjusting the Tone control, you can enhance high frequencies for clarity or reduce them to avoid harshness.

4.1 Setting Up the Pedal in Your Effects Chain
To integrate the Keeley Compressor Plus into your setup, place it early in your effects chain, typically after tuning pedals but before overdrive or distortion. Start with all controls at their midpoint (12 o’clock position) for a neutral base tone. Adjust the Sustain and Level knobs to balance compression and output volume. Use the Attack Switch to optimize response for single-coil or humbucker pickups. Fine-tune the Tone control for desired frequency balance and engage the Blend control for natural transparency. This configuration ensures a smooth, expressive sound.
4.2 Basic Controls and Their Functions
The Keeley Compressor Plus features intuitive controls designed for precise tone shaping. The Sustain knob adjusts the compression level, controlling how long notes ring out. The Level knob sets the output volume, ensuring your tone remains balanced. The Tone control fine-tunes the frequency response, while the Attack Switch optimizes compression for single-coil or humbucker pickups. The Blend control mixes compressed and dry signals, preserving your guitar’s natural feel. These controls work together to deliver a transparent, dynamic sound tailored to your playing style.
4.3 Advanced Techniques for Optimal Compression
For optimal compression, experiment with blending compressed and dry signals using the Blend control to maintain natural dynamics. Adjust the Attack Switch to suit your guitar’s pickups, ensuring smooth transition between single-coil and humbucker tones. Fine-tune the Sustain and Level knobs to balance compression and output, preventing overly squashed or weak tones. When using humbuckers, reduce the Sustain slightly to avoid excessive compression. For single-coils, increase the Attack for clarity. Practice these techniques to achieve a polished, professional sound tailored to your playing style.
