Why these settings

The Mustang LT25 lacks a dedicated physical presence knob, so highs are pushed via the treble control and the onboard overdrive block. Keep the mids around 6 rather than fully scooped to preserve the punchy mid-forward attack of the Jose-modded Marshall. The single-coil/angled bridge pickup on the Jamster requires a slight bass bump and tone wide open to mimic the massive output of an Invader humbucker.

PRO TIPAnchor your palm firmly across the bridge saddles for fast, percussive downpicked muting, and strike near the bridge pickup to accentuate the sharp upper-mid harmonics characteristic of early Metallica riffing.
