Why these settings

The LT25's British amp models nail the Marshall mid-forward voicing Slash uses. Mids pushed to 7 recreates his signature bark; treble at 6 avoids the fizz that digital Marshall models can produce. Gain at 6 gives crunchy rhythm without losing note definition—Slash's tone is driven but never saturated into mush. Rolling the Les Paul's tone knob to 7 tames the bridge pickup's ice-pick and adds that buttery Slash smoothness.

PRO TIPSlash's rhythm attack is all in the pick hand—he digs in hard on downstrokes and lets up slightly on upstrokes, creating a natural dynamic pump. Use the fat part of a medium pick angled slightly, and stay over the neck pickup's pole pieces even when using the bridge pickup for a thicker attack.
