“Full featured pedal that covers a lot of bases! I have had the Stratus for about six months. On my board it fills a multi-purpose role... it has performed flawlessly in all situations.”

"Rich tone! I use the Stratus mainly in a worship setting. The effects I have strung together in my Stratus furnish beautiful finishing tones to my chain. Since space is at a premium, I appreciate its small form factor."

"This is a killer pedal that will totally simplify your life! This pedal is an absolute beast, and steal of a deal, considering everything it can do. I really like the quality of the effects."

This thing is a BEAST. [Stratus] is made really well - it's nice and heavy, in a standard foot-pedal form factor. The Stratus app is easy to use... [it] sounds GREAT. Well done, Chaos Audio."

"Seriously amazing, love it for practice. Really great sounding and simple to use... I could envision this pedal being the center of a great fly rig. Great job and keep up the good work!"

"I love that the effects sound great, it’s easy to switch between them, and the build quality is really high! If you’re looking for a way to have dozens of effects, you can’t go wrong with the Stratus!"

Michael Y

Verified buyer

"It's remarkably versatile with tons of unique and high quality sounds. I'm currently using it in conjunction with my existing physical pedal board ... and it's growing in abilities extremely quickly."

David K

Verified buyer

"... After checking out what the pedal does I knew I wanted one so I was in on the initial launch order. From hard hitting gritty distortion and fuzz to luscious reverbs and swirling modulations, the possibilities are endless."

Dave M

Verified buyer

"Wow! The Stratus pedal is a great addition to any pedalboard. I went from having 8 pedals down to 4. And, the multitude of choices ... helps come you come up with many different textures. A must have for any gigging guitarist."

Jason C

Verified buyer

"I got my Stratus right after Christmas and it’s been so fun to dive into the different tones and pedalboard variations. I’d like to highlight their Chorus and Fuzz, their algorithms are great! And it plays well with my other analog pedals on my board."

Josh R

Verified buyer

"[Stratus] was beautifully packaged and arrived safely. It fired up and connected to my iPhone with no issues and I had a blast playing around with all the different effects. The interface feels like playing with real pedals. I recommend it fully."
