Abstract: A portable speaker system for an electric string instrument such as a guitar. The portable speaker system has a housing including an audio jack for receiving a raw audio signal from a guitar, an amplifier, a speaker, and a power supply. The portable speaker system attaches to the guitar by a button connector which releasably attaches to a strap button of the guitar, and a stabilizer for inhibiting rotation of the portable speaker system when attached to the guitar. The portable speaker system portably generates output sound from the raw audio signal. The portable speaker system can couple with a portable computing device, which can process the raw audio signal and provide a supplementary audio signal, from which the portable speaker system can portably generate output sound.
