Boss Acoustic Singer Live

Excellent price/quality ratio

I use the small combo for small gigs with family and friends. The sound is excellent at a more than sufficient volume to be accompanied by a cajon or a smaller set of drums/percussion. You have delay, reverb, and chorus available, effects that will definitely enrich your sound. At the microphone input (since you have two at hand, instrument and microphone) you also have a harmony effect, meaning a harmony effect, either in low, unison, or high, to make any voice sound fuller. If you're alone and feel like jamming, you also have a looper available, which you can record for about 40 seconds, plus unlimited overdubs. By the way, the looper pedal is included and it's dual. It can also be used to start/stop the harmony effect, for example.
At the back of the combo, you have various inputs and outputs to record directly or to amplify to a larger PA, auxiliary input in case you want to sing over recordings, etc. Plus, the small combo is extremely portable and easy to handle, takes up very little space, and all this at a reasonable price.
In conclusion, the small Boss ACS is a very versatile tool, with quality sound, easily transportable, that can offer you very cool musical moments, whether with friends or alone, wherever you are. Rock on.
