Let There Be Rock Boogie Duel — Gretsch Engine & SG Solo
The song comes from the Vanda and Young era, when the band was recorded for live impact with Malcolm’s Gretsch rhythm separated from Angus’s lead guitar. Album-level evidence supports Malcolm’s Jet Firebird and Marshall foundation, while the exact Angus guitar and amplifier used on the master remain uncertain; the SG and Marshall values below are therefore representative.
