Repulsive in its splendid beauty amp settings — Line 6 Spider iv 15 watt

The Crowbar guitar tone for “Repulsive in its splendid beauty”, dialed in for a Line 6 Spider iv 15 watt with a Kramer Striker HSS. Studio version, Crowbar self-titled album (1993)

Original rig

Gibson SG or Les Paul (humbucker, bridge) → Boss MT-2 Metal Zone → Randall RG100 solid-state amplifier. Kirk Windstein's signature sludge tone: high-gain, thick saturation, mid-forward but massive low-end.

Thick and saturated, sludgy and massive, tight percussive attack, crushing sustain, aggressive and biting, dense and compressed, solid-state harshness, wall-of-sound heaviness

Running into clean amp would be ideal, but Spider Insane channel already has gain—use the SD-1 as a front-end boost to add grit and tighten the low-end. Keep Tone rolled back to avoid fizz stacking with the amp's digital distortion.

Why these settings

The original uses a Boss MT-2 into a Randall solid-state for that tight, scooped-but-thick sludge tone. Your Spider IV's Insane channel approximates high-gain solid-state aggression. The SD-1 isn't a Metal Zone—it's warmer and mid-focused—so I'm using it as a boost to add saturation and tighten the low-end rather than as the primary dirt source. Gain at 7 (not maxed) prevents the Spider's digital artifacts from dominating. Mid pushed to 6 compensates for the Insane channel's natural scoop and gets closer to Windstein's mid-forward sludge.

PRO TIPWindstein picks hard directly over the bridge pickup with a very deliberate attack—that percussive 'chunk' is as much technique as gear. Dig in with the pick angled slightly and let each note bloom into sustain rather than picking lightly and relying on gain alone.
