Review: Works! - Good acoustic pedal, does what it is designed to do! I was recommended this pedal over much more expensive ones. I have used it now on about 30 shows, some inside some outside and 2 arenas. It works! Flawless in every detail, warm and rich tone, no feedback, and as a DI box it’s perfect!
Review: Great for simple acoustic piezo DIY pickups - So far so good. No complaints. I use this to compensate for my donner piezo pickups inside a cheap classical guitar. I use this pre amp to turn down bass and treble, because the piezos are a little noisy. Works great. I'm glad this worked out because everyone was recommending a pre amp that cost 3x the amount of the Caline. I couldn't swing it on my first project. I would recommend this for anyone doing a simple acoustic guitar pickup project, that just needs a good sound for practice, open mics and garage banding.

### ⭐⭐⭐⭐ Great pedal for the price
*by D***N on July 21, 2025*

Great pedal. Does exactly what it’s supposed to. My only complaint, and it’s a niche one, is for my pedal board purposes the in and out are on the wrong sides. However when I’m using the xlr out for live gigs that’s a non issue. Definitely a great buy for the price point.
