Artist usage
Add artistAndy Bell uses the Maxon CP-9 Pro+ Compressor/Limiter, as evidenced by a Reddit post by user InfiniteTristessa, which details his pedalboard setup while touring with Ride in 2025.
"Maxon, a Japanese company, makes a wonderful, musical compressor that I love to use in the studio. It is of very good quality so I can use it in recordings and the studio. It doesn't enhance your sound like some compressors, rather it compresses and limits your output to make for easy recordings that sit well in the mix. I will be covering more compressor reviews in the next few videos...I hope you watch!" - Juan Alderete

Jeff Kendrick uses the Maxon CP-9 Pro+ Compressor/Limiter, as evidenced in a 2008 photo on Pinterest by Daniel Brophy Music & DJ, showcasing his guitar signal chain.
"My pedalboard setup is fairly simple - Besides a tuner and a wah pedal the four other pedals I use are all made by Maxon. Starting with perhaps my favorite pedal the CP-9 Pro + Compressor - I pretty much leave the CP-9 on all the time. I like to think of it as a quality control pedal for my overall tone. It is really hard to describe what a difference the CP-9 makes in boosting all the great and desirable overtones and leaving the unpleasant ones out. I'm not sure how Maxon dialed this one in so accurately, but they did!"
