01Blackstar LT Metal
Use as a gritty boost, NOT full metal saturation. Cobain's DS-1 was set with moderate gain to slam the front of his amp. Keep gain LOW — this is grunge crunch, not djent. Run into amp's CLEAN channel if you want tighter response, but OD channel at low gain works here.
Your MG15G is a solid-state Marshall with scooped, modern voicing — Cobain's tone was mid-heavy and raw, so I've pushed mids to 8 to compensate. The LT Metal is a high-gain pedal, but Cobain's DS-1 was used at moderate gain for grit, not saturation — keep your gain at 3 max. Your Les Paul's humbuckers are hotter than Cobain's Univox/Mustang pickups, so the lower pedal gain balances output.
