Sabine is an American manufacturer of professional audio signal processing equipment, founded in 1971 in Gainesville, Florida by Doran Oster. The company began as a guitar repair and flute manufacturing shop before expanding into electronic products with the MT-4001 quartz metronome and, in 1987, the ST-1000 chromatic tuner, which became the best-selling chromatic tuner in the United States by 1990.

Sabine is best known for pioneering the world's first automatic feedback controller, the FBX Feedback Exterminator, in 1990. The FBX line — including models such as the FBX-SOLO SL-620, FBX-901, FBX1200, FBX1210, FBX2020, FBX2400, and FBX2410 — uses adaptive narrow-band parametric notch filters to detect and suppress feedback frequencies in live sound systems. The technology earned a 1991 TEC Award for Outstanding Technical Achievement and became a fixture in live venues, theaters, and houses of worship.

The company's catalog also includes wireless microphone systems such as the SWM7000 series and the SACOM digital wireless line, which integrate onboard FBX feedback control, compressor/limiter, and de-esser processing. Headquartered in Alachua, Florida, Sabine manufactures its FBX products in the United States.

Sabine has 4 products cataloged on Equipboard, including Effects Processors, Tuning, and Tuners. Their gear is featured by 2 artists, with the strongest followings in Rock and Metal. Notable users include Jordan Eberhardt and Leo Leoni.
