Nice little amp for acoustic guitar. I play in a church ensemble and the Loudbox Mini easily and clearly projects the sound of my Taylor grand concert model to the back pews of a church seating 160 without distortion. Both my wife and our pianist had the same reaction: "it sounds so warm!" compared with the electric guitar amp I had been using. Very little problem with feedback, it also has a phase switch which I haven't needed. Easily portable at ~ 19#. Others have commented that the thin vinyl covering tears easily, but I tote it around with its cover and I've had no problems. The reverb and chorus effects sound fine. I haven't simultaneously used the mike channel while playing guitar so I can't vouch for how well it handles a two-input load. For solo guitar at least, it's a nifty acoustic amp with surprising warmth, clarity, and projection for its size.
