V-Tone Acoustic ADI21 : Great for indoor use

First of all, this is one great sounding and silent pedal. I bought it to get rid of the piëzo 'quack' of my acoustic electric and found out that 1. it does get rid of it and makes my acoustic electric sound like an acoustic guitar; 2. it is a tone shaper and gives you control over your tone and 3. it adds saturation to your sound if you wish.

It's also quite usable for bass guitars and works as a passive DI.

I bought it for a live acoustic gig. It did very good, This thing has only two flaws:

1. The switch is flimsy plastic and easy to break;

2. While it has an XLR out, it cannot be powered with phantom power but runs on batteries or an external adapter.

I use it in my studio on bass and acoustic guitars. I will never put it on a stage with a band.
