R&B Artist Keyshia Cole ‘Blings’ Out Her Harmonica Mini | Placid Audio Custom Microphones

Sitemap

Placid Audio was started in Dallas, Texas by bass player and engineer Mark Pirro (Polyphonic Spree/Tripping Daisy) in 2003 as a vehicle to facilitate small batch production of his first prototype microphone, The Copperphone. With emphasis on durable build quality, attractive design and distinctive sonic character, Placid Audio has been honoring these aspects as the company has grown over the last several years.
