01ROCK DIRT
Onboard stomp block — acts as DS-1 style boost tightening the Mesa front end
The 90S ROCK model captures the aggressive Mesa/Boogie preamp saturation Kurt tracked for the main riff. Because the Harley Benton ST-20 has thinner, brighter single-coil pickups than Cobain's DiMarzio bridge humbucker, bass is pushed to 7 and treble pulled to 6 to retain low-end chunk without ice-pick harshness. Clean verse: roll guitar volume back to 3 or bypass the ROCK DIRT stomp block. Middle has no knob on the LT25: press the encoder to open the preset, press it again on the amp model, then select MIDDLE on the display and turn the encoder.
