The AD-2 is a preamp and D.I. Box for acoustic guitars. It has a built in dual band EQ so you can fine
tune the low and high frequencies. It also features a treble boost to push the end when you need it.
Another very helpful addition is the anti-feedback circuit. This is very useful for live performances.
