Intelligent Processing for Natural Sound

When you first plug into the CP-1X, you’re in for a totallynew guitar compressor experience. Typical stompbox compressors color andrestrict your sound, and are hard to dial in for various playing styles. Theinnovative CP-1X eliminates these drawbacks and more, opening up a world ofexpressive potential. The powerful MDP engine analyzes your guitar’s manydifferent tonal elements in real time, providing natural compression thatintelligently follows and adapts to your playing. With this high-tech approach,your true tone and technique always comes through, even when using aggressivesettings for that effected “squish.”

Tap Into New Levels of Musical Expression

No matter what kind of guitar or style you play, the CP-1Xalways delivers rich, musical tone. From mellow phrases and arpeggios to heavyrhythms, fast solos, and beyond, every playing nuance remains detailed anddefined. The pedal also provides superior performance for chicken pickin’country licks, funky rhythm grooves, and other standard guitar compressorapplications, and works great as a booster thanks to its punchy, transparentsound. On seven- and eight-string guitars, the CP-1X easily controlsupper-range dynamics without compromising your powerful low-end tone. And whenused with acoustic-electric guitar, the natural, lush overtones are fully preservedas 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 iswhat you get. Not so with the CP-1X, as the pedal’s controls interact with eachother at a highly detailed level. When you turn a knob, numerous interlockedparameters are adjusted under the hood at once. This gives you dynamics controland tone shaping ability that far exceeds standard compressor pedals, providingresults previously attainable only with high-end studio processing. The goodnews is that you don’t need to be a sound engineer to use the CP-1X—itssophisticated MDP processing has been meticulously fine-tuned by the BOSSengineers to let you dial in ultra-polished tone with familiar stompboxcontrols.

High-End Features for Pro Performance

The CP-1X features pro-level 18-volt input circuitry thatprovides ample headroom for the hottest guitar pickups, ensuring exceptionalclarity with any instrument. A 16-segment gain reduction indicator clearlydisplays 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 othercompressors, another huge benefit brought by BOSS technology.

MDP: Advanced Tech, Superior Tone

Leveraging decades of research and development, BOSS’sproprietary Multi-Dimensional Processing (MDP) technology offers a freshapproach to achieving exceptional guitar tones. In real time, MDP analyzes thevarious elements that make up the sound, including frequency, overtones,dynamics, pickup response, and more. Various playing characteristics areanalyzed as well, such as note register, single notes vs. chords, bends,vibrato amount, and others. Each individual element is then processed in uniqueways to produce optimized tones as you play. With its ultra-detailed, high-techapproach, MDP delivers tone quality and playability that reaches far beyond thelimits of traditional effects processing.
