Originally voiced to match Dave Mustaine's favourite bridge pickup from the Rust In Peace sessions, the Thrash Factor set now comes in six colour and cover options.
Seymour Duncan has expanded the colour options for its Dave Mustaine Thrash Factor humbucker set, with the pickup now available in black nickel, gold, nickel, matte black, white and zebra finishes.

The Thrash Factor has its roots in a specific guitar Dave Mustaine used heavily during the recording of Megadeth’s 1990 album Rust In Peace. That guitar was loaded with a Seymour Duncan JB in the bridge and a ’59 model in the neck, and Mustaine noted that particular JB had a character he couldn’t find in a standard off-the-shelf unit. Seymour Duncan worked with him to figure out why, ultimately modifying the winding process to match it. The result sits apart from a standard JB: tighter low end, slightly scooped mids and more aggressive highs.
The set pairs that modified bridge pickup with Mustaine’s preferred neck pickup, the SH-1n ’59 model. Both come printed with his signature, and all variants use black nickel hardware regardless of the cover finish chosen.
Hand-built in Santa Barbara, California, the Thrash Factor is a high-output passive humbucker – so no battery required, just a direct drop-in for most guitars routed for humbuckers.
The Dave Mustaine Thrash Factor set lands in Australia in mid-September 2026 through Australis Music Group.
