	When IGL opened on June 1, 1965, its equipment list was as follows: one Ampex 3-track recorder using 2" tape, two Ampex 4-channel mixing consoles, four Electro-Voice Sentry monitors, one McIntosh amp, two Neumann M49 mics, one Neumann U67 mic along with other mics, outboard gear, stands and cabling. A single track Ampex recorder was purchased in 1966. Then, in 1972, an Ampex 2-track mastering recorder and an Ampex 8-track recorder were added to the facility along with more outboard gear. The studio space was also expanded and modified around this time to better serve the clientele.
