The shimmering clean riff that drives Blue Öyster Cult's classic. Buck Dharma cut it not on his signature SG but on co-producer Murray Krugman's hollowbody Gibson ES-175, chosen for its warmer, woodier jangle, through a clean Music Man 410-65 combo at the Record Plant in New York. The shimmer comes from the hollowbody plus an EMT plate and a 15-ips tape delay tracked live — not a chorus pedal. Standard tuning, A-minor riff.
