Megadeth’s Dave Mustaine lists mega-estate in San Diego County’s rural Fallbrook

Megadeth co-founder Dave Mustaine has listed his estate in Fallbrook for sale at $5.375 million.

The lead singer and guitarist of the metal band owns a sprawling 9.5-acre spread in the northern San Diego community that includes vineyards, pastureland and a pond.

The country English-style main residence, built in 1990, is reached through gates and a long winding driveway. A red British phone booth sits outside the gates.

Inside, rock and stone work, decorative painting and soaring ceilings with heavy beams give the 5,345 square feet of living space a castle-like air. Leaded and stained glass, wrought ironwork and 10 fireplaces add to the overall Old World ambiance.

Living and dining rooms, a paneled media room/den, a bar, an office, a gym, five bedrooms, five full bathrooms and two powder rooms are among the living spaces.

A state-of-the-art sound and recording studio occupies what once was a pool house. A control room, a reception room and a producer’s boarding room are among the facilities.

A guesthouse/carriage house sits above the detached three-car garage. Well water is used for irrigation.

Mustaine, 54, was the original lead guitarist for Metallica before he and bassist David Ellefson formed Megadeth in 1983. The influential thrash metal band will release its 15th studio album, “Dystopia,” next year.
