I saw this recommended in some buskers' groups, and I wanted to try it because it s lightweight and cheap. While of course it cannot compare to "good" amplifiers, I was really impressed by how good it sounds. There are some controls for the sound, gain etc, and they work, I was particularly impressed by its lack of feedback, like, my Roland has more feedback than this one, ZERO feedback. It s not very loud but for a single instrument it s quite ok, I tried it with a loop with voice and guitar and if you are in a quiet place it does provide some amplification. +1 because of the look, it looks like a toy from the 1970s/80s but it feels very sturdy (no but, those toys were made to last forever). Definitely an eye catcher.
