Review: Great effects - Sounds great , easy to use , love it when listening thru ear phones , very emersive experience
Review: Best of both worlds - Watched a video on youtube, and decided to order this. I have played saxophone over 15 years and never got into the effects side, but I'm glad I did. This works well with violin, harmonica, and acoustic guitar as well. I have a bandmate that plays saxophone. Definitely a game changer.

### ⭐⭐⭐⭐⭐ Great effects
*by D***N on February 10, 2026*

Sounds great , easy to use , love it when listening thru ear phones , very emersive experience

### ⭐⭐⭐⭐⭐ Best of both worlds
*by M***W on November 20, 2025*

Watched a video on youtube, and decided to order this. I have played saxophone over 15 years and never got into the effects side, but I'm glad I did. This works well with violin, harmonica, and acoustic guitar as well. I have a bandmate that plays saxophone. Definitely a game changer.

### ⭐⭐⭐⭐ Great EXCEPT Looper
*by M***T on October 27, 2023*

The effects on this pedal are great for getting a variety of sounds out of your guitar. If you play sets with a variety of genres you should get it. I play everything from Prince to Tom Petty and Toby Kieth. I like switching between the presets to adjust to the feel of the songs I’m playing. I don’t like the looper function because you have to use your finger to activate it. It would be much more functional if you could get to it on the fly with the foot pedals. You can always buy an additional foot pedal but it’s just another thing to pack.
