01Boss DS-1 Distortion
Primary gain source direct into amp input (double-gain prevention active: amp gain set low on Twin Clean model)
The Boss DS-1 provides the primary dirt to emulate Cobain's DS-2 distortion running into a clean Fender platform. The Mustang LT25's Twin Clean model keeps the amp headroom uncompressed, so amp gain is pulled down to 2 to prevent muddy double-gain artifacts while the pedal handles the saturation. The LT25 faceplate lacks a middle or presence knob, so mid shaping is voiced via the DS-1 Tone knob and flat amp treble. For the solo, dig into the DS-1 with your pick attack or engage your Small Clone with Depth switch down for subtle modulation.
