Petty's studio was innovative for its time, featuring mastering and disc-cutting equipment (which meant he could present finished, ready-to-press masters to record companies), and a small apartment where performers could stay between sessions. An on-site radio transmitter allowed artists to hear exactly what their music would sound like over the airwaves. Rather than an hourly rate, Petty would charge per finished recording, allowing for more experimentation than may have otherwise been possible.
