The Shure Unisphere 588SA is a vintage dynamic microphone featuring Shure’s respected Unisphere cardioid design, offering focused pickup, strong midrange presence, and excellent rejection of background noise and feedback. Built during Shure’s golden era of microphone manufacturing, the 588SA has long been valued for live vocals, harmonica, guitar amplifiers, PA systems, and speech.

The Unisphere capsule delivers a warm yet articulate sound, with a forward midrange that helps vocals and instruments cut through a mix without harshness. Its rugged, road-ready metal construction makes it ideal for stage use, while its vintage character also appeals to collectors and studio users seeking classic Shure tone.

The 588SA variant includes an integrated on/off slide switch, making it especially practical for live performance. A reliable and great-sounding microphone, the Unisphere 588SA remains a favourite among musicians who appreciate vintage gear with real-world usability.

This mic is in good working order but has some solid residue on the top of the mic but this does not affect the sound at all.
