Across many continuities, Sonic the Hedgehog has been shown to have an aptitude for or interest in the electric guitar, although he is also seen playing an acoustic one on occasion.
The designs of Sonic's personal guitars have also shared some similarities over the years. In both Sonic Underground and the Sonic Boom TV series, he plays a triple-neck guitar, and both his guitar from the early 90s Sonic the Hedgehog manga and his aforementioned Sonic Underground one have their bodies shaped to resemble his quills in some fashion.
Ironically, Sonic was not the guitarist in the infamously scrapped Sonic the Hedgehog Band, but instead its lead singer. While other media has since had Sonic sing, it's rare for his talents as a vocalist to ever be emphasized.
