Description

Introducing the Boss CP-1X Compressor Effects Pedal, a groundbreaking stompbox that's designed to elevate your guitar performance. Harnessing the power of BOSS' Multi-Dimensional Processing (MDP) technology, the CP-1X analyses your guitar's signal in real time, providing dynamic control while preserving the unique characteristics of your tone and technique.

The CP-1X's four-knob interface makes it easy to dial in sophisticated results, while the handy gain reduction indicator clearly displays the amount of compression being applied. This ensures you are always in control of your sound, enabling you to tap into new levels of musical expression with ease.

Key Features:

  • Powered by BOSS's proprietary Multi-Dimensional Processing (MDP) technology that analyzes your guitar's tonal elements in real time for a dynamic and authentic sound.
  • Simple four-knob interface for easy adjustments and sophisticated results.
  • Handy gain reduction indicator that provides a clear visual of the compression being applied.
  • Optimized for all types of guitars, making it versatile and suitable for every style of music.

High Quality Compressor

This is a studio quality compressor. Super low noise pedal with four normal knobs (Level, Attack, Ratio, Compression). I really believe in Boss pedals. Must buy one!

I was surprised when I fired up the CP-1X at the amount of clarity and definition it gave me. It really seemed to follow and adapt to everything I played. No matter what style I played, this compressor always seemed to react in a musical way. Whether it’s country picking or very aggressive clean R&B or heavy rhythm or even distorted lead soloing, it always enhances what I’m doing.
