I didn't think a DI would make THAT much difference to my acoustic guitar sound, but I was very wrong. I wanted to make my acoustic guitar set-up stereo, as I use some effects pedals to create a wash with a low mix underneath the dry acoustic tone. I use stereo tape delay, and stereo reverb, and come out into the JDI. I don't know if it's the Jensen transformers or what's going on in that magic green box, but the richness and clarity of sound beats any other DI I've ever used. I could not recommend this more for acoustic guitar purposes. The foam on the underside peels off very easily, making attaching it to a pedalboard a doddle.
