Multieffekt For Acousticguitar : Great concept, not as impressive as advertised

Many reviews are raving about this device, and it is quite fun and shocking to hear effects coming out of the soundhole out of your acoustic guitar. But once the surprise wears off, I feel it takes away from the natural sparkle and projection of my guitar. It ends up only really sounding great when amplified (either with a mic - which is why all the ads sound so gread - or by plugging it in), which kinda defeats the purpose of the device. Because in an amplified scenario, a pedal would be cheaper, have more functionality and could be operated by foot mid-song.

The dials are not very precise. You need to turn it several clicks to move to the next effect. Quickly moving over a few effects at once isn't possible, because it will register four quick clicks to the right as moving over one effect. Then wait a second, en then turn again for the next effect. This might get frustrating during a show.

There is a slight constant high-pitched buzz as long as the device is turned on. All the effects do have an unpleasant, high-pitched ring to it and at any volume that I was able to hear them, muddied up the natural sound of my guitar.
