The intended purpose of this speaker is for parties as its name suggest, and they did a great job at making it for that purpose. The sound can reach a very loud level and the quality is good. It has a plug for a guitar and as shown in the pictures has knobs on top to adjust the sound whether its the bass, echo, or treble and this doesn't just just apply to the guitar output as it also can be used to adjust the output of the microphone if you are using that.
