Master of Puppets by Metallica — Amp Settings & Guitar Tone
Reference tone dialed on a Squier Classic Vibe Stratocaster into a Fender Mustang LT25. Settings below are cited from real sources; open the page in a browser for the interactive version, or get this tone dialed for your exact gear.
To recreate the iconic thrash metal tone of 'Master of Puppets,' we'll use the Fender Mustang LT25's 'Thrash Overkill' preset as a starting point, adjusting the EQ to achieve the scooped mids and high-gain saturation. The Squier Classic Vibe '60s Stratocaster will substitute for the Explorer, focusing on its bright single-coil pickups to cut through the mix.
