Don't Forget

A smart, multi-band compressor that lets your true tone shine through.

Powered by BOSS’s MDP technology, the CP-1X is a new type of multi-band compressor for guitar that preserves the character of your instrument and technique for unlimited musical expression. Intelligent processing analyzes your signal in multiple dimensions as you play, providing advanced dynamics control that never colors or muddies your tone like typical stompbox compressors can. The simple, four-knob interface makes it easy to dial in sophisticated results, while the handy gain reduction indicator always shows you how much compression is being applied. Optimized for all types of guitars, the CP-1X offers next-generation performance for every style of music.

Intelligent Processing for Natural Sound
When you first plug into the CP-1X, you’re in for a totally new guitar compressor experience. Typical stompbox compressors color and restrict your sound, and are hard to dial in for various playing styles. The innovative CP-1X eliminates these drawbacks and more, opening up a world of expressive potential. The powerful MDP engine analyzes your guitar’s many different tonal elements in real time, providing natural compression that intelligently follows and adapts to your playing. With this high-tech approach, your true tone and technique always comes through, even when using aggressive settings for that effected “squish.”

Tap Into New Levels of Musical Expression
No matter what kind of guitar or style you play, the CP-1X always delivers rich, musical tone. From mellow phrases and arpeggios to heavy rhythms, fast solos, and beyond, every playing nuance remains detailed and defined. The pedal also provides superior performance for chicken pickin’ country licks, funky rhythm grooves, and other standard guitar compressor applications, and works great as a booster thanks to its punchy, transparent sound. On seven- and eight-string guitars, the CP-1X easily controls upper-range dynamics without compromising your powerful low-end tone. And when used with acoustic-electric guitar, the natural, lush overtones are fully preserved as you go from gentle fingerpicking to full-chord strums.

Studio-Level Results with Simple Controls
With the knobs on most pedal compressors, what you see is what you get. Not so with the CP-1X, as the pedal’s controls interact with each other at a highly detailed level. When you turn a knob, numerous interlocked parameters are adjusted under the hood at once. This gives you dynamics control and tone shaping ability that far exceeds standard compressor pedals, providing results previously attainable only with high-end studio processing. The good news is that you don’t need to be a sound engineer to use the CP-1X—its sophisticated MDP processing has been meticulously fine-tuned by the BOSS engineers to let you dial in ultra-polished tone with familiar stompbox controls.

High-End Features for Pro Performance
The CP-1X features pro-level 18-volt input circuitry that provides ample headroom for the hottest guitar pickups, ensuring exceptional clarity with any instrument. A 16-segment gain reduction indicator clearly displays the compression amount, making it easy to see what the pedal’s doing. The CP-1X’s noise performance is also extremely low in comparison with other compressors, another huge benefit brought by BOSS technology.

MDP: Advanced Tech, Superior Tone
Leveraging decades of research and development, BOSS’s proprietary Multi-Dimensional Processing (MDP) technology offers a fresh approach to achieving exceptional guitar tones. In real time, MDP analyzes the various elements that make up the sound, including frequency, overtones, dynamics, pickup response, and more. Various playing characteristics are analyzed as well, such as note register, single notes vs. chords, bends, vibrato amount, and others. Each individual element is then processed in unique ways to produce optimized tones as you play. With its ultra-detailed, high-tech approach, MDP delivers tone quality and playability that reaches far beyond the limits of traditional effects processing.

  • Great comp


  • no cons.

Best Uses

  • Guitar or anywhere you need to control dynamics

Comments about Boss CP-1X Compressor Pedal:

A compressor only amplifies what it receives. You send it a noisy signal its going to increase that noise depending how much squash you use. Single coil pickups in a noisy room with a comp set to hard, noise! The neck of the guitar acts like a antenna, you can move to the left or right and find a quieter spot. A ISP Decimator II will take care of that issue quickly and leave your tone intact.

      Comments about Boss CP-1X Compressor Pedal:

      So, I like many Boss pedals. I really like the advanced signal processing in a few of the newer pedals (e.g., DA-2). And this sounds good. Very musical. As a compressor it is different and very cool sounding. But it is a tad noisy for me. The noise makes it no advantage compared to the comps I use now (Keeley, Wampler). You may like it. Would not dissuade you from trying,

        Comments about Boss CP-1X Compressor Pedal:

        I wanted to have a floor-mounted compressor pedal without the grit feature and saw this Boss pedal. I know how the compressor works in line with the signal and how it is subtle on the tone of the guitar. This pedal ups the voltage to 18 internally and the difference is clear. I did not hear any loud 60 cycle noise, just a trace, but not audible when playing. The 4 controls are familiar to me, so I think the effect does what it was designed to do. I have the Tera Echo, so I hear the difference in the MDP technology in this pedal, too. I placed this compressor first in line to test it out, but, I could see it last in line also. You've got to hand it to Boss for upgrading their chip sets to get new sounds from their older versions. I'd say try this pedal if you want a compressor without any germanium clipping to distort your axe, Eugene.
